Drive Car Using Water
by Zouking
1. Slow down your speed
As stated above, slow down your driving speed. Everyone knows this, but not many uses it. Well, it is a proven fact that dragging your engine will increase your fuel consumption rate. It is your choice to decide what speed you want to travel at.
2. Close Your window
Open your window when driving will increase the turbulence in your car and eventually your car will need more fuel to move. use the build in ventilation instead.
3. Plan your route
Try to plan your route before you head off. A route with more traffic light and heavy traffic is always not a good idea. The shortest route however may not be the best route if you are required to stop a lot. Try to avoid route that have a lot of high gradient slope or uneven road.
4. Top up your tank at Arco
Well, this is my personal comment. Every year, other major petrol company are making millions and millions or profit from us driver. They keep on advertising their new product such as Techron, V-power which they put in expensive stuff into them to order sell them at a higher price. In fact, all the petrol as basically the same, just that they claim their petrol have a cleaner burning combustion and better fuel efficiency. I am getting my top up at Acro at the moment and I never had any trouble with their quality.
But I sometimes do go to Chevron for a top up as well. I will put in exactly 8 gallons into my tank in order to qualify for a discount at the car wash section.
Another tips is when I traveling on the road, I try to keep note of the petrol price along the way. If I happen to see the price goes down, I may consider topping up. Some petrol station does offer a free cup of coffee with a fill up.
Manual transmission is great. I strongly encourage everyone to try using it. By using manual transmission, you can pretty much decide if you want a sport shifting at a higher rounds per minute (rpm) or a fuel efficiency shifting at a lower rpm. No matter how 'clever' the car claimed to be, it is never more clever than a human head.
If you are already driving a manual transmission now, and wish to save some fuel as well. Remember this golden rule, shift up early, shift down late.
5. Disable that cruise control
If you have the cruise control and the road is clear ahead, by all means use the cruise control. It will keep your speed constant, thus there is no need for you to accelerate. But if the road is not clear, you will be wasting a lot of fuel. Remember to use that overdrive function. It helps to keep your rpm low. Go into neutral gear when your car is standing still, to reduce and cool off the transmission.
6. Reduce your car overall weight
Another law of physics. You should try to remove those junk at the boot of your car. But keep the spare tire and other gears. You never know when you will need them.
7. Turn off your engine.
Even when your car is not moving, it is still using your fuel. If your air con is on, it takes up even more fuel. So if you know that you will be in the spot for more then 5 minutes, consider switching off the engine.

Who Killed The Electric Car? : New Jeep hybrid car 2009
Who Killed The Electric Car?
by Gillfinn
The auto makers and you have conflict of interests. They sure can produce cars which will last longer than you want, require no expensive service and no gasoline. You want such a car, but the manufacturers want to make sure they keep getting steady income from far more profitable SUV sales, car maintenance, and the oil companies - income from the fuel sales, be it gasoline or hydrogen. EVs are so good that require none of that so you’d pay very little to nothing for your car maintenance and your personal “gas station” is as far as the nearest electrical outlet. So what do you think auto makers will sell you - what’s good for you or what’s good for them? They afraid of EVs, they try very hard (and unfortunately succeeding) to convince you that no one wants electric cars. They can make EVs if forced by law but at first opportunity they destroy perfectly normal EVs (sad GM’s EV1 story). Hard to believe? Yes, this is unfortunate but well documented fact. Despite long waiting lists, they try to convince you there was no demand. EV1’s of course were never advertised. Simple truth is, they never offered EV1’s for sale to the general public precisely because they knew there was demand. If they would offer EV1’s, the public would demand more, GM would be pressured to work against their business interest, so they simply decided to only lease the vehicles putting such lease conditions that very few would qualify, which is “proof” no one wanted EV1’s. Can you buy EV1 or RAV4? How about Ford’s Think City or Ranger? No. GM scrapped its EV program, and despite long waiting lists, kept telling “there is no demand” while never allowing anyone to buy a single EV1 vehicle and destroying them at the end of lease. If you want to know more about it get “who killed the electric car” movie. Today (2008) they GM changed the tune and promises Chevy “Volt”. We’ll see. But I’m afraid based on the past history of promises and deliveries, you will die waiting for Detroit. EV technology exist today. Far less complex, electric cars would cost less than gas ones if produced in the same quantities. You can compare the costs of ownership of ICE vs. EV. A word about fuel cell (FC) vehicles, namely ones using hydrogen as an energy source. Don’t hold your breath to see them any time soon if ever. A FC vehicle is no doubt a step in right direction in a sense that inefficient internal combustion engine is replaced with an electric motor. The only difference between pure battery EV (BEV) and FCEV car is the energy source; the drive systems and control electronics are almost identical. However, instead of just a plain rechargeable battery, FCEV has to carry a very complex hydrogen reformer using exotic expensive materials, full of pumps, blowers, hoses, and a tank of liquefied or compressed hydrogen you need to keep putting in. Fuel cell manufacturers claim that they are quiet since contain no moving parts. Did you have a chance to stay next to a working fuel cell vehicle? I did. A FC itself is sure quiet, but all necessary supporting equipment (blowers and pumps) make far more noise than modern ICE engine. Here is an example of “quiet” FC for a city bus demonstrated at Michelin challenge Bibendum event in California in 2003. A FC car will have scaled down version of all these components. When it runs, you can’t keep a conversation unless you move 50 feet away. For the record, the serious work on FC started in the 60’s and GM back then announced that practical FC car for masses is “around the corner”. Well, today, 50 years later, we’re still wondering about location of that corner…and still waiting. Why? Well, sorry, regardless of your opinion on this subject, it’s because of the cold and unpopular in PR fact of reality: MONEY. Auto makers say fuel cell cars are clean an environmentally friendly. But so are EVs, which are even cleaner, considering charging from solar, hydro or wind sources. Auto makers sure are pro environment, but as long as you keep buying fuel and keep servicing overly complex vehicles. Doesn’t matter what type of fuel, as long as they are in control of your pocket, they’re happy. Are you happy too? Not to mention who exactly gets the money for all that imported oil… Have you questioned anyone how much energy is needed to produce a hydrogen you’re going to pay for? You need electricity to run the equipment reforming hydrogen to the useable for FC form. And then, the hydrogen is going to be used to get back electricity to run a vehicle propulsion motor. What’s wrong with this picture? Isn’t it simpler, cheaper, more efficient and just plain makes more sense to just store initial electricity directly in a car’s battery in the first place? Hydrogen is an extremely clever scam. When you step back and ask, “Where will the hydrogen come from?” the house of cards falls apart. You will get hydrogen from fossil fuels. The most economic way to get hydrogen is to catalyze natural gas. When you do this, you throw away 50% of the fuel value. If you were to put that hydrogen into a fuel-cell car, it would only go 50% the distance (at best) that a hybrid car would, if fueled from the natural gas directly. The oil company loves it. They get to sell twice as much per mile driven. It is also twice as much CO2 per mile driven. (G.W. = Global Warming)If you choose to make hydrogen for your fuel cell car from electricity, an EV using that electricity directly will go at least twice as far.Many of the foaming advocates of hydrogen say, “But we can figure out a way to make hydrogen more efficiently if we hurl big research dollars at the problem.” Unfortunately, there are only so many hydrogen atoms in each methane molecule. Also, until we unlock the secret of photosynthesis, there will be no efficient way to make hydrogen. Batteries will always be more efficient at storing electricity than hydrogen gas.Think of all the money we have spent on fusion power and it will give you just a peek of how much we would have to spend on electrolysis to make it more efficient. There are many many other areas in alternative fuels that will reap greater rewards on a faster timetable for far less money. (Like biodiesel) Of course, the oil companies really wouldn’t like that, would they. Can an EV run far? Well, if an EV could run more than 340 miles on a single charge 10 years ago, you’d think that today technology can be only better, especially if part of the money going into FC research would be spent advancing EV batteries. Can it run fast? Is about 300 mph fast enough for you? Can it be quick? How does 0-60 mph in 3.6 seconds sound? Can you own an electric car for every day use? Yes! If you’re fed up with Big three, motivated enough and have a handy man skills or can get help, you can convert a conventional vehicle to an EV yourself. Or you can buy a conversion made by other EVers. Thousands have done it. You too can make a difference.http://www.gillfinn.mionegroup.com

Jeep Tops: Anatomy of a Jeep top
by: Billy Han
Jeep tops are fairly universal Jeep accessories in that everyone from casual Jeep owners to hardcore off road enthusiasts has some basic knowledge of what they’re about. But Jeep tops can get more complicated that one might think, and while it’s hard to go wrong when making a purchase, having an intimate knowledge about them can go a long way in extending the benefits. For this reason, we’ve dissected nearly every imaginable Jeep top to take an in-depth look at what makes them must-have Jeep accessories. Which Jeep Top? It’s an age old question; perhaps one that has been asked since the time of the dinosaurs. Not really, but choosing a Jeep top has always been a decision that requires a fair amount of thought. At first glance, choosing a top seems pretty simple. The features are all plainly stated, pictures give you an idea of what to expect looks-wise, and your particular environmental situation further dictates which one you need. But there are also many factors that aren’t taken into account when shopping for a Jeep top. Intangibles like installation and frame style are examples of lesser-known aspects, while things like road noise or insulation are factors that can only be experienced firsthand. With this in mind, I’ll do my best to cover aspects that are typically unaccounted for. Factory versus Aftermarket Jeep Tops When it really comes down to it, there isn’t a huge discrepancy between what both factory and aftermarket tops have to offer. A factory Jeep top will give you that genuine Jeep look and feel, plus the added security of sticking to true Jeep accessories that follow the same standard of quality as the vehicle itself. Aftermarket tops are for the most part similar to factory units, but with a few exceptions. Although both versions of Jeep tops are made from the same materials, equivalent quality, and with the same purpose in mind, aftermarket tops offer certain features, benefits, or other Jeep accessories that you might not get out of factory units. For instance, certain aftermarket tops have been optimized to reduce road noise better than a factory one. Also, in the event that your Jeep top needs replacing, aftermarket replacement options are typically cheaper than factory tops. For these reasons, aftermarket options usually make for favorable Jeep accessories when replacing aging factory tops. Narrowing It Down The first and most obvious way to categorize Jeep tops in terms of need is by splitting up hardtops and soft tops. Clearly, the two styles are distinctive enough that each one serves its purpose in different ways. Jeep Hardtops Hard-style Jeep tops are a never-fail option. They rarely if ever need replacing and provide enhancement and heavy duty protection. In addition, they offer a number of handy Jeep accessories, like power windows, a rear window defroster, and more. Hardtops come in a one-piece model, or a two-piece configuration with a removable sunroof. On the flipside, Jeep hardtops are not easily removed and stored for those who enjoy open-air summertime driving. Hardtop hoists and storage-based Jeep accessories are available, but require added purchases. Jeep Soft Tops For those who love customizability with their Jeep accessories, soft tops are the way to go. Available in a variety of designs, Jeep soft tops offer the kind of versatility, comfort, and style that justify a Jeep purchase in the first place. Plus soft tops are easy to install, remove, or store. On the other hand, soft Jeep tops aren’t exactly ideal for colder weather. Their thinner material and fabric construction leaves them with poor insulation, and also gives them an average lifespan of only 3 to 5 years before requiring replacement. Upon Further Review... On the other hand, soft Jeep tops aren’t exactly ideal for colder weather. Their thinner material and fabric construction leaves them with poor insulation, and also gives them an average lifespan of only 3 to 5 years before requiring replacement. Jeep Hardtops When it comes to hardtops, making a choice and meeting the requirements for installation is relatively easy, and getting the right Jeep top is usually a simple matter of picking either a one or two-piece top. Two-Piece Hardtops The two-piece hardtop is the definitive Jeep top for year-round performance in any climate. On one hand, you get the protection and insulation of a full-fledged hardtop during the winter. Then for warmer weather conditions, the cockpit features a removable roof piece for open-air driving. In addition, hardtop Jeep tops come with a vast assortment of unique features and Jeep accessories like a fiberglass-reinforced plastic composition for durability, an in-mold gel coating for fade resistance, rear window vents, a rear window defroster, tinted tempered glass windows, an overhead dome light, and much more. One-Piece Hardtops In addition, hardtop Jeep tops come with a vast assortment of unique features and Jeep accessories like a fiberglass-reinforced plastic composition for durability, an in-mold gel coating for fade resistance, rear window vents, a rear window defroster, tinted tempered glass windows, an overhead dome light, and much more. Jeep Soft Tops Soft tops are where matters can get a little confusing. To start, it is necessary to determine whether or not you have a pre-existing frame, and whether it’s in usable condition. Remember that the frame is the backbone of your soft top, and therefore a worn, rusted, or misshapen frame can cause your Jeep top to install improperly, or perhaps not perform as expected. If you do have a frame already in place, you next need to find out if it’s a factory or aftermarket frame. This will ultimately help you narrow down which aftermarket Jeep top options are available to you, since certain Jeep tops are only compatible with particular frame styles. For those without a Jeep top frame altogether, an aftermarket Jeep top kit that includes both the Jeep top and hardware system to set it up is suggested. Pre-Existing Factory Frame Jeep Tops These Jeep tops are designed exclusively for use with Jeep vehicles that have a pre-existing factory frame in usable condition. Replace-A-Tops For a fast, efficient, and inexpensive soft Jeep top solution, Replace-A-Tops make updating your old, worn factory top simpler than ever. The Replace-A-Top is a basic Jeep top skin that easily slips on and off your factory frame. Each kit includes only the Jeep top fabric with optional clear or tinted windows, and the Jeep tops themselves are built to factory standards, or better. Additionally, the Replace-A-Top includes a host of other fine features, such as premium fabric construction, mildew and UV resistant material, industrial strength thread, heat sealed seams, and much more. Trusted Jeep tops manufacturers Bestop, Rugged Ridge, and Smittybilt each offer perfectly reliable and inexpensive Replace-A-Top models. Bestop also offers a premium option in their Replace-A-Top Jeep top made out of revolutionary Sailcloth fabric to help improve insulation and drastically reduce road noise over factory Jeep tops. Halftops For a sporty two-seater look and feel there’s nothing quite like a Halftop Jeep top. Combining components of several other styles, the Halftop is the perfect hybrid of unique style and rugged function. The Halftop includes all the usual soft top functions and Jeep accessories like mildew and UV resistant-fabric, a convenient fold back sunroof, zip-out windows, and much more, but then also incorporates all of this into an unconventional sporty look. The Halftop Jeep Top from Bestop is actually something of an exception when it comes to having the right hardware for installation. It can accommodate those who have a pre-existing factory hard or soft top frame, or for those who have no frame at all. Halftop Jeep tops are available exclusively from Bestop. No Frame or Aftermarket Frame Jeep Tops These Jeep tops are compatible with Jeeps that have either no soft top frame whatsoever, or a pre-existing aftermarket frame. Supertop You wouldn’t think from the sleek design and intuitive features that the Supertop Jeep top has followed mostly the same formula for decades. Sold as a complete package with all necessary mounting hardware and Jeep accessories to get your started, a Supertop is a simple yet dependable solution for adding a soft top to an open-top Jeep. Its “Set-N-Stretch” fabric won’t fade or warp regardless of temperature, and the zip-out replaceable windows come in clear or tinted. The Supertop also gives you a variety of other premium features like mildew and UV resistant fabric, industrial strength thread, heat sealed seams, heavy duty molded-tooth zippers for easy window installation and removal, and powder-coated rust-resistant frame hardware to ensure long frame life. Best of all, using the Supertop framework, you can easily change out your top skin for a bikini top, or remove it altogether for open-air driving. The Supertop Jeep top is available exclusively from Bestop, and is available in a complete kit with frame hardware or in replacement skins for those with an aftermarket frame already installed. Rollback Sunroof Tops These soft top Jeep tops follow the same basic formula of most other soft tops with the exception of a sleek and convenient rollback sunroof for a more open-air feel. These Jeep tops also include all the necessary hardware you need to do a complete installation from scratch, and the versatile design also allows for compatibility with a number of soft door options. Other features of Rollback Sunroof tops include mildew and UV resistant fabric, industrial strength thread, heat-sealed seams, heavy duty molded-tooth zippers for easy window installation and removal, and powder-coated rust-resistant frame hardware to ensure long frame life. Current rollback sunroof-style Jeep tops include the Bestop Sunrider and Pavement Ends Flip Top. Tiger Top Vintage and classic Jeep owners need not feel left out thanks to the Tiger Top. Designed and custom-crafted by Jeep tops leader Bestop, the Tiger Top Jeep top is built specifically for older model Jeeps, and even comes sporting that vintage Jeep look. The Bestop Tiger Top includes all necessary hardware for a full installation onto an open top Jeep. Your Jeep Top Purchase Choosing a top isn’t as complicated of an affair as one might suspect. In the end, Jeep tops are all about getting the style you want at an agreeable price. Hopefully this article has helped you in that decision-making process in order to minimize the hassle of buying and installing the right one so you can focus on the fun part. Now go get your Jeep top.

Jeep Wrangler Rubicon Express SYE Slip Yoke Eliminator Installation : New Jeep 4 wheel review 2008
Jeep Wrangler Rubicon Express SYE Slip Yoke Eliminator Installation
by Dorian Jepsen
It's now common knowledge that Jeep Wrangler owners like to have fun and what's more fun than a bigger Jeep? Not much!
The problem Wrangler owners deal with when lifting their Jeep is that short rear driveshaft. Any amount of suspension lift that exceeds 3.5" is likely to cause driveshaft vibrations. Aside from lowering the transfer case (which also lowers ground clearance), the easiest way to eliminate driveshaft vibrations is to get rid of the factory, slip-yoke type driveshaft and replace it with a longer, CV type. The only way to do that is to replace or modify your existing transfer case.
Replacing the transfer case can be expensive -- upwards of a couple thousand dollars. Unfortunately, most people probably don't have that kind of money available to spend on a transfer case swap. That leaves the option of modifying the existing transfer case by removing the tailcone output section and shortening it by about 3". Doing this will allow you to install a driveshaft that is about 3" longer which will alleviate driveshaft angles, but better yet, it will allow for the installation of a CV type drivehsaft which better at handling sharp angles than its slip-yoke counterpart.
Installing a Rubicon Express slip yoke eliminator takes about two hours and requires the following tools.
Basic mechanics wrenches/sockets
Circular saw/grinder with a metal cutting blade (a Sawzall will not work)
Center punch
Hammer
Electric drill
Tap handle - for the 3/8" tap.Do not use a wrench to turn the tap.A wrench does not allow you to put equal force on both sides of the tap like a handle does and therefore you can easily break it off inside the shaft.
1/8" and 5/16" drill bit
3/8" and 5/16" Allen wrenches
Cutting oil
RTV silicone sealer
Loctite
The advantages of using this particular kit are simple: it's cheap ($199 USD), easy to install (done without removing the transfer case from the vehicle), improves your lifted vehicle's rear driveline angle, and allows a lowered transfer case to be put back into its stock location.
Remove the rear driveshaft from the vehicle.On the rear axle, this is done by removing four 1/4" bolts and two steel retaining straps from the differential output yoke. At the transfer case, simply pull the driveshaft out of the slip yoke. Some oil may spill from the transfer case when the shaft is removed but not a lot.
Remove the tailcone section from the transfer case.The tailcone is held to the transfer case by three bolts. Remove them and tailcone should pop/slide off the case/shaft. If not, lightly tap it on the sides with a hammer to nudge it free from the case. The only thing holding it in place at this time is silicone sealant.
Seal the output shaft bearing surface to avoid contact with debris.You can use duct tape or even Reynold's saran wrap. Be sure to use a liberal amount so no debris can get into the output bearing when cutting the shaft off.
Measure and mark the shaft so that 1" of splined shaft will remain.Always follow the rule, "Measure twice. Cut once." It may be wise to mark a little more than 1" of shaft because too long is better than too short. If you cut the shaft too long, it can be shortened. If you cut the shaft too short, you'll need a new one. You will need a circular saw with a metal cutting blade. A 4.5" hand grinder is ideal for this because it's small enough to fit in the confined area you'll be working in. When using a grinder, make sure you cut slowly and no more than 30-60 seconds at a time. This will prevent the shaft from getting overheated and warping. After you've cut through the shaft, if it isn't square at the end, grind it down to make it square.
Center punch the end of the shaft.This will ensure the drill bit starts in the center of the shaft when drilling the pilot hole. To find the center of the shaft easier, place the CV Output Flange over the cut-off output shaft. This reduces the visible surface area from about 1.25" diameter to 0.5" diameter and will allow you to find the center of the shaft easier. Be sure to hit the centerpunch hard enough to put a dent in the end of the shaft deep enough for a 1/8" drill bit to seat into.
Drill the pilot hole into the end of the shaft.This is done with a 1/8" drill bit. This step is easiest done with the vehicle raised on jack stands. With the vehicle being as high as possible, you'll be able to sit under it and guage the direction of the drill. The pilot hole needs to be drilled into the shaft as straight as possible so take your time. The pilot hole needs to be 1"-1.25" deep. Once completed, you'll need to bore out the 1/8" pilot hole with a 5/16" drill bit. To be on the safe side, you may want to use a 3/16" bit before going to the 5/16" bit. This makes it easier to drill a straight hole. Make sure the final depth of the pilot hole is 1.25".
Use a 3/8" -24 tap to cut threads into the 5/16" pilot hole.Use cutting oil and keep the tap threads clean. CAUTION: If you have never used a tap before, then tapping the pilot hole is not the time to learn! For best results you should read an article on how to correctly do this and then practice on another piece of steel. The proper way to tap a hole is one full turn forward (clockwise) and one-half turn back (counter-clockwise), but since the shaft is made of hardened steel, tap it in one-half turn forward increments. Better safe than sorry at this point.
Install the Oil seal in the Bearing/Seal Flange.You will need a press, vice, or similar tool to do this. The oil seal needs to be pressed in straight or it will be damaged. Afters the Oil Seal is pressed into the Bearing/Seal Flange, turn it over and run a bead of RTV Silicone along a circumferemnce just inside the three bolt holes. The bead should be about 3/16". Allow about 10-20 minutes for the silicone to "skin" over before installing it. Take this time to lube up the rubber part of the seal where it will make contact with the CV Output Flange. Wiping transfer case oil on it with your finger will be adequate. Make sure to put oil all around the black rubber part of the seal. Faliure to do this will melt and tear the seal within the first mile of driving.
Install the Bearing/Seal Flange.Remove whatever material you used to protect the transfer case output bearing (in step 3) from the transfer case output shaft. Clean the surface near the bearing making sure there is no leftover residue from when the tailcone was removed. Use three grade 8 M10 x 25mm bolts to install the Bearing/Seal Flange onto the transfer case. Apply Loctite to the bolts before inserting them. Now would be a good time to apply RTV silicone to the remaining splines of the output shaft. This will prevent oil from leaking through the CV Output Flange after it's installed.
Install the CV Output Flange.Slide the CV Output Flange over the output shaft splines and through the oil seal. Take caution not to damage the seal. You may need to use a hammer to lightly tap the CV Output Flange down the shaft. Use a 3/8" bolt and washer to bolt the CV Output Flange to the output shaft. Use loctite to hold the bolt in place.
Congratulations! You no longer need to worry about your Jeep vibrating due to your 3"+ suspension lift. ---------- Wrangler Parts

Jeep Tops: Anatomy of a Jeep Top
by Billy Han
Jeep tops are fairly universal Jeep accessories in that everyone from casual Jeep owners to hardcore off road enthusiasts has some basic knowledge of what they're about.
But Jeep tops can get more complicated that one might think, and while it's hard to go wrong when making a purchase, having an intimate knowledge about them can go a long way in extending the benefits.
For this reason, we've dissected nearly every imaginable Jeep top to take an in-depth look at what makes them must-have Jeep accessories.Which Jeep Top?
It's an age old question; perhaps one that has been asked since the time of the dinosaurs. Not really, but choosing a Jeep top has always been a decision that requires a fair amount of thought.
At first glance, choosing a top seems pretty simple. The features are all plainly stated, pictures give you an idea of what to expect looks-wise, and your particular environmental situation further dictates which one you need.
But there are also many factors that aren't taken into account when shopping for a Jeep top. Intangibles like installation and frame style are examples of lesser-known aspects, while things like road noise or insulation are factors that can only be experienced firsthand.
With this in mind, I'll do my best to cover aspects that are typically unaccounted for.Factory versus Aftermarket Jeep Tops
When it really comes down to it, there isn't a huge discrepancy between what both factory and aftermarket tops have to offer.
A factory Jeep top will give you that genuine Jeep look and feel, plus the added security of sticking to true Jeep accessories that follow the same standard of quality as the vehicle itself. Aftermarket tops are for the most part similar to factory units, but with a few exceptions.
Although both versions of Jeep tops are made from the same materials, equivalent quality, and with the same purpose in mind, aftermarket tops offer certain features, benefits, or other Jeep accessories that you might not get out of factory units.
For instance, certain aftermarket tops have been optimized to reduce road noise better than a factory one. Also, in the event that your Jeep top needs replacing, aftermarket replacement options are typically cheaper than factory tops. For these reasons, aftermarket options usually make for favorable Jeep accessories when replacing aging factory tops.Narrowing It Down
The first and most obvious way to categorize Jeep tops in terms of need is by splitting up hardtops and soft tops. Clearly, the two styles are distinctive enough that each one serves its purpose in different ways.
Jeep Hardtops
Hard-style Jeep tops are a never-fail option. They rarely if ever need replacing and provide enhancement and heavy duty protection. In addition, they offer a number of handy Jeep accessories, like power windows, a rear window defroster, and more. Hardtops come in a one-piece model, or a two-piece configuration with a removable sunroof.
On the flipside, Jeep hardtops are not easily removed and stored for those who enjoy open-air summertime driving. Hardtop hoists and storage-based Jeep accessories are available, but require added purchases.
Jeep Soft Tops
For those who love customizability with their Jeep accessories, soft tops are the way to go. Available in a variety of designs, Jeep soft tops offer the kind of versatility, comfort, and style that justify a Jeep purchase in the first place. Plus soft tops are easy to install, remove, or store.
On the other hand, soft Jeep tops aren't exactly ideal for colder weather. Their thinner material and fabric construction leaves them with poor insulation, and also gives them an average lifespan of only 3 to 5 years before requiring replacement.Upon Further Review...
On the other hand, soft Jeep tops aren't exactly ideal for colder weather. Their thinner material and fabric construction leaves them with poor insulation, and also gives them an average lifespan of only 3 to 5 years before requiring replacement.Jeep Hardtops
When it comes to hardtops, making a choice and meeting the requirements for installation is relatively easy, and getting the right Jeep top is usually a simple matter of picking either a one or two-piece top.
Two-Piece Hardtops
The two-piece hardtop is the definitive Jeep top for year-round performance in any climate.
On one hand, you get the protection and insulation of a full-fledged hardtop during the winter. Then for warmer weather conditions, the cockpit features a removable roof piece for open-air driving.
In addition, hardtop Jeep tops come with a vast assortment of unique features and Jeep accessories like a fiberglass-reinforced plastic composition for durability, an in-mold gel coating for fade resistance, rear window vents, a rear window defroster, tinted tempered glass windows, an overhead dome light, and much more.
One-Piece Hardtops

Soft tops are where matters can get a little confusing.
To start, it is necessary to determine whether or not you have a pre-existing frame, and whether it's in usable condition. Remember that the frame is the backbone of your soft top, and therefore a worn, rusted, or misshapen frame can cause your Jeep top to install improperly, or perhaps not perform as expected.
If you do have a frame already in place, you next need to find out if it's a factory or aftermarket frame. This will ultimately help you narrow down which aftermarket Jeep top options are available to you, since certain Jeep tops are only compatible with particular frame styles.
For those without a Jeep top frame altogether, an aftermarket Jeep top kit that includes both the Jeep top and hardware system to set it up is suggested.Pre-Existing Factory Frame Jeep Tops
These Jeep tops are designed exclusively for use with Jeep vehicles that have a pre-existing factory frame in usable condition.
Replace-A-Tops
For a fast, efficient, and inexpensive soft Jeep top solution, Replace-A-Tops make updating your old, worn factory top simpler than ever.
The Replace-A-Top is a basic Jeep top skin that easily slips on and off your factory frame. Each kit includes only the Jeep top fabric with optional clear or tinted windows, and the Jeep tops themselves are built to factory standards, or better.
Additionally, the Replace-A-Top includes a host of other fine features, such as premium fabric construction, mildew and UV resistant material, industrial strength thread, heat sealed seams, and much more.
Trusted Jeep tops manufacturers Bestop, Rugged Ridge, and Smittybilt each offer perfectly reliable and inexpensive Replace-A-Top models.
Bestop also offers a premium option in their Replace-A-Top Jeep top made out of revolutionary Sailcloth fabric to help improve insulation and drastically reduce road noise over factory Jeep tops.

Jeep Wrangler, One Of The Worst : New Jeep Wrangler 2009
Jeep Wrangler, One Of The Worst
by AnthonyFontanelle
Consumers in the auto industry get assistance from organizations and companies through reports and lists. Some companies and organizations would do research and then later on send out the results of the tests they did on cars to check some of its aspects. There are also those who would do tests and then compile the vehicles tested and send out a list containing the top ten or the worst ten vehicles on such a category.
Consumer Reports is one of these companies who try to help out consumers through reports of the tests that they have done on vehicles. One of the most recent lists from the company shows eleven of the auto industry’s worst cars and sports utility vehicles. It is a totally unpleasant experience to be included in the list. Sure you may be having much exposure because you are included in such a list but you are also going to lose quite a number of sales for the possibility that people would not buy your car is quite high. That is the case with the Jeep Wrangler Unlimited and its Jeep Wrangler parts. See, out of a possible 100 as a score, the Jeep Wrangler Unlimited was only able to take home 17 points.
According to Consumer Reports, the vehicle’s strong point is that it can go through the off road and yet give the driver and passenger much enjoyment for no road is too tough for the vehicle. The vehicle has proven that going through the off road is going to be a wonderful experience if you are using a Jeep Wrangler Unlimited. Now that is where the list of advantages ends. See, Consumer Reports enumerated that the Jeep Wrangler Unlimited should still get some work on its handling, its ride, and its braking. The vehicle is also not fuel efficient and is also quite a noisy vehicle. Comfort is something that you could not find especially if you are in the front row.
With these noted, one would be able to answer the question why the Jeep Wrangler Unlimited has taken home such a low score and has been considered one of the worst vehicles in the industry today. Of course, the world is not all just about the off road and consumers are looking for vehicles that are not just off-road material but could also be used for an ordinary person’s usual everyday duties.
