    The JKS Jspec two and a half inch lift kit for your 2007 and up four-door JK is going to be a very well built and very complete lift kit that's going to perform very well on road and off the road. Now the J control version of this lift kit is going is going to be more expensive. It's also going to include some additional components, like some control arm brackets to help correct for your pinion and your caster angle in the front of your Jeep, where this kit is not going to have that. So can you run two and a half inches of lift without any sort of caster and pinion correction? Yes. If you decide you do wanna run some sort of pinion or caster correction, you can always add a set of control arm brackets or a set of adjustable control arms which will also add some articulation to your jeep. We'll talk a little bit more about that in just a second.A kit like this that's at two and a half inches is going to be for those of you who wanna run roughly a 35-inch tire, still have some room to flex, that's going to be a combination that looks really good but also works very well on-road and off-road. Now JKS does provide a very well built, well put together lift kit that does include a set of Fox shocks. And even though these aren't the top of line Fox shocks, this is still going to drive the price of this lift kit up a little bit. So when you're looking at JKS, you should expect a well built fairly complete kit, however, you are going to pay a little bit more because of the quality of the components that are included.This kit includes a set of four new coil springs which are going to provide those two and a half inches of lift, and these are going to be a dual rate coil spring. Now there's much to debate about what is best, a linear, dual rate, triple rate, or a progressive rate spring. The dual rate that come in this kit are going provide a fairly comfortable ride when you're at ride height, but also a slightly stiffer spring when you do get down to close to a coil bind situation. So they're going to be good for off-road as well as on-road.As I said, this does come with a set of Fox shocks for that new taller ride height. These are going to be Fox Adventure Series 2.0 shocks. Now these aren't going to be the T6061 aluminum that the higher end Fox shocks are, these are going to be an alloy that are covered in a powder coat finish, instead of just a clear anodized finish, but either way, they're still going to provide a really nice ride. These are going to be a nitrogen charged shock. And the nitrogen charged in that shock is there to eliminate any sort of bubbling or cavitation that you can get in the shock fluid when you work that shock really hard over time. Working a shock over a long period of time or hitting some higher speed washboards can cause some shock fade, and a nitro shock will have a lot less of that, help to eliminate any kind of shock fade. Now in general, a nitro shock will ride harder than a hydro shock, but most of the ride quality does come down to valving, and that's something a Fox does really well. So you're still going to get a comfortable ride from these shocks while still getting the benefits of that nitrogen charge.Here you have a front track bar that comes in this lift kit. This is going to be an adjustable track bar that's much stronger than the factory bar. The factory track bar can start to flex when you get a larger tire on your Jeep. This is going to give you zero flex, so you're not going to have any wobble type feeling, and this is of course adjustable, so you can fully center that front axle underneath the Jeep. Over here you're going to have a rear track bar bracket. This doesn't provide you with quite as much adjustability as some of the other ones out there, you're not going to be able to change the roll center, it doesn't give you three different positions for mounting your track bar, however it is a very well built, very stout track bar that's going to get the job done, moving the mounting point up a little bit, flattening out the track bar angle, and working very well to get you back on the road again.Over here you have a set of JKS quicker disconnects for the front of your JK after you get your lift kit installed. And I really like these sway bar disconnects. These are going to be adjustable so you can get the length exactly where you want it, and you can disconnect these from not just one side but both sides, allowing you to completely remove them and through them in the Jeep, as opposed to some of the others that just allow you to disconnect from one side and then fold them up out of the way. These are also gonna be greaseable, they fit very tight, so you're not gonna get any rattles, and because they are greaseable and made of high-quality materials, they're going to last you a good long time. The kit's also going to include all the hardware necessary to get it installed, as well as some brake line relocation brackets that are going to be necessary to ensure you don't pull a brake line taut when you're off-road. This is gonna be a two outta three wrench installation that will take three hours to get it done. This isn't a kit that includes control arms, so you're not going to have to do that additional work, which will cut down on the time a little bit. You're gonna wanna have a socket set and some wrenches handy, of course a jack and some jack stands. If you have access to a lift and either pneumatic tools or electric tools, it'll definitely speed the process along. And I always recommend spraying all of the applicable nuts and bolts with a good penetrating oil well before you get started. That time spent is going to pay dividends in the end, speeding up your installation. Now, with any lift kit, the first step is going to be jacking up the Jeep and supporting it by the frame, then removing or loosening anything that keeps the axles from completely drooping. So that's going to be your sway bar end links, your brake line brackets, your track bars, and of course your shocks. That'll allow you to completely sag those axles and pop out the factory springs. At that point, you can replace your factory springs with your new taller springs, and as you reassemble, swap in your new components. So bolt up those new shocks, new sway bar end links, and track bars, and track bar brackets as you're reinstalling all of those parts. Again, this is something that's probably gonna take you around three hours, give or take, depending on the tools you have at your disposal, but it is something you can do in your drive way.This is a $1,200 lift kit, and a lot of that cost does come from the Fox shocks. Fox does make a premium product, they do charge a little bit more for them, and even though these aren't Fox's top of the line shocks, they are gonna be more expensive than some of the other kits out there that have a more no name style of shock with them. But you're not just paying for the shocks with this, you are getting a lot of components and you're getting a lot of high-quality components from JKS, which are going to make this lift kit ride really well and last a long time. So, in my opinion, this is worth the $1,200 price tag. So if you're looking for a high-quality two and a half inch lift kit, I definitely recommend the JKS Jspec two and a half inch, that you can find right here at extremeterrain.com.

    Would the rear track bar relocation bracket be strong enough for the long run or should I buy Rough Country Forged Rear Adjustable Track Bar?

    Mike

    • The track bar and track bar bracket in the JKS Jspec 2.5 in. Lift Kit will be strong enough for light off roading and street driving, but for extreme off road, a forged track bar would be a good piece of insurance.

    I already have a Teraflex leveling kit installed. WOuld i be able to use the spacers on this kit to lift the front end a bit more? In the videos and pictures it still looks like there is a factor rake after install. Or is that due to front bumper weight?

    AndrewH

    • The springs on the JKS Jspec 2.5 in. Lift Kit are intended to get rid the factory rate but depending on the weight in the front end with heavy after market bumpers, winches, etc. you may notice some sagging. We would suggest installing a small spacer like .75 inches to level out the sag if you notice any. You can install the spacers from the Teraflex leveling kit with this lift but you would then need to purchase new shocks as you would over extend the ones included in the kit.

    • The JKS Jspec 2.5 in. Lift Kit will have everything you need to get your wrangler lifted and back on the road. You will want to be sure that you get an exhaust spacer with this kit if your wrangler is a 2012-2018 JK. Some suggested upgrades to this kit would be: Adjust Control arms/Control arm brackets. Another great upgrade to compliment this kit would be a rear adjustable track bar.

      Great ride better than stock

      Overall I am very impressed with the handling and ride from this list. Everything included is of high-quality and looks great. It would be nice for a few dollars more to include the rear sway bar ends instead of relocating the stock ends. I am also installing front lower control arms because I did not want to install the cam washers for this stock LCA's. The ride is very solid, flat and my Jeep looks great. it is a little stiffer than stock. Installation was straightforward. The instructions have lots of pictures and there are lots of videos online to help out on installation. I did the installation by myself in the driveway with two floor jacks and Jack stands which took about 5 to 6 hours. This was the first lift that I have installed. If I were to do it again I could probably take 1 to 2 hours off of that time. I have researched many lifts for the last month when I settled on the JKS Jspec 2.5 While this lift may not be the cheapest but it is complete and has many great quality parts. You will not be disappointed with this lift kit. Overall the front lifted up just under 3.75 inches and the rear 2.75 inches over stock. I am running heavy steel bumbers.

      Wow, great lift and can’t wait to get some 35’s and toss out the 33s. The JKS Jspec quick disconnects are very convenient and the adjustable track bar seems very durable. I drove 14 hours to Colorado this past weekend and didn’t have one problem. Also the Fox Shocks definitely made the Jeep ride smoother. Mike

      Great kit!

      Very well put together kit. The quality of the parts is apparent straight out of the box. I had no major complications on the install. It took a little longer than expected, but I like to take my time. My only regret is not buying lower control arms at the same time, as I’m not a huge fan of the cam-locks on the front. Great ride improvement both on and off road. Wish I had done this sooner.

      Review from JKS Jspec 2.5 in. Lift Kit (07-18 Wrangler JK 2 Door)

      Very complete and capable kit

      I installed the JKS Jspec 2.5 lift kit on my 2011 Jeep Wrangler Sport. I went with this kit because it comes with high quality components, including quick disconnect sway bar links for the front, fox shocks, dual rate coil springs, and a beefier adjustable track bar. I've had the lift kit on for about 2 weeks. It seems to have settled by now. This past weekend, I re-torqued everything down to spec. It drives better than stock on the road. The shock and coil springs combo work great together. My whole jeep used to have a lot of movement over speed bumps, pot holes, and minor off-road trails. The new shocks and coil springs make a noticeable difference in absorbing that movement. I'll say that I don't think longer control arms are necessary, but they may improve the ride even more, especially if you plan on doing any sort of wheeling. I plan on adding some down the road. I run a 33" duratrac tire. With this kit, there is plenty of room for articulation with that size tire. You could probably run a 35" tire, but you may rub on the trail. If you plan on installing this in your drive way, I recommend buying a cordless impact wrench. Makita makes a 3/8" drive that packs a ton of power. It can fit in most tight places. You'll also need some good jack stands, and a floor jack. If you have these basic tools, installation is a breeze. However, you could certain get it done without the impact. After installing the track bar, make sure you re-align the steering before driving. If you don't, the traction control sensor engages, and automatically applies the brakes.

      Great On-Road and Off-Road Experience

      I had been running on 33's with a stock build for some time and finally decided on this 2.5 lift kit. Held up fantastic 4x4 in Moab and has drastically improved my on-road driving! The additional steering stabilizer is a must have, I wish I had it sooner. I was worried about the look of the 2.5 inch lift, but needless to say, I was pleasantly surprised by the beefy, clean build look it gives.

      Review from JKS Jspec 2.5 in. Lift Kit (07-18 Wrangler JK 2 Door)

      Great Product

      Install: Products are of very high quality, and were easy to install, with the only exceptions being -One of the front lower shock mount bushings had to be seated with a vice and was too large and had to be trimmed for installation -Drilling/tapping a proper hole for the front bump stop extensions was much more difficult than indicated The directions were overall very clear. I decided to go with a front Currie Antirock instead of the JKS Quicker Disconnects, so I cannot speak to that portion of the install. Of note, I ended up getting 3" in the rear and 3.25" in the front despite having a winch and oversized spare/heavy equipment in the "trunk." Ride quality: Fantastic ride and really grabs the road, but I noticed the biggest distance when it gets on uneven dirt.

      Decent lift

      Install went pretty well, and the instructions were nice and clear. However, some of the components would not fit. The replacement bolts they sent (for the Rubicon version) with the anti sway links would not fit through the factory Anti sway bar. The quick connects that were also included, would also not fit through the bolt holes of the anti sway bar without modification. Not wanting to drill my sway bar out, I utilized the factory bolts that were instructed to discard in the instructions. Installation took 7 hrs by myself using floor jack and jack stands in my garage.

      I love this kit!

      After 1.5 years of looking at kits and trying to find the perfect one, someone told me about the JKS Jspec 2.5. After looking through the reviews and watching countless videos on it, I purchased it. The price seems a bit steep, but I am telling you now, this kit is 100 worth it. Remember you get what you pay for. The addition of the front adjustable track bar and Fox shocks are what pushed me towards buying it, and I couldn't be happier with my choice. Plus all the benefits JKS gives on their products (check their site for details) you will not be disappointed, promise. The handling on and off road are about as close to perfect as you can get with a lift, if you install it correctly. Now this kit will take you about 6 hours with a friend and the correct tools. But I am telling you now, it is worth it. Thank you JKS and ET for this product, 5 stars across the board!

      The jspec 2.5in lift looks and feels amazing. Great for that little extra clearance and beefier look without having to do extra mods to make it work. Great price for everything thats included and the ride is smoother than ever. The quick disconnect sway bars make terrain travel a sintch. With the right tools it only took 4hrs to do the full install and alignment. Would definitely recommend.
