    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.

    With this kit does it come with everything you need and do you recommend any esle to go with it

    LoganM

    • 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.

    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.

    With this kit, do I need other hardware like JKS Control Arm Correction Bracket kit?

    MarcoC

    • This lift kit will have everything you need to get your wrangler lifted. It is highly recommended that you will need the JKS exhaust extension kit. When lifting a Jeep it can throw off the caster. But, the Control Arm Correction Bracket kit will help to correct your caster when you install the lift kit. We also recommend to get an alignment once the lift kit is installed.

      Great kit!

      First off, the parts were extremely well packaged! A little bummed out by a 4 week back order for the shocks but overall happy with everything. Only reason for 4 stars is it seems one of the brake line brackets was bent the wrong way during manufacturing, I’m still waiting to hear back from JKS and hopefull they will send me a correct one. It’s a very complete kit and install is straight forward, no huge issues along the way. A little time consuming. Ride is very similar to stock (hard to compare switching to load range E tires).

      My kit was on backorder. Took 4 weeks to get here. Not a big deal, just thought I would mention it. I ended up getting 3’ inches of total lift out of this lift. Super solid solid kit pretty easy install. I opted to order the Rear Adjustable Track Bar and adjustable End Links. No drilling required when you do this option.

      JKS Jspec 2.5 in Lift Kit 2015 JKU

      Great product, quick delivery, fairly good installation instructions. Installation was performed in garage, by myself, off of jack stands. Biggest challenges were torquing front and rear track bars to 125ft/lbs with no room to work. Second challenge was that the rear track bar was hitting the rear correction bracket/brace attaching to the rear axle. Had to reverse the direction of the bolts 180 degrees. Once completed came together very nicely.

      Great so far.

      Took a buddy and I about 7 hours to do the install, along with a full set of adjustable control arms. Installing the new rear trackbar bracket was a huge pain, other than that it was fairly straight forward. Because I added control arms, and also because I managed to untrue my steering wheel, I need an alignment. Will update review after I have a chance to test out the ride quality

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

      JKS 2.5 Lift Kit

      This lift took me and a helper 7 hours to complete. It dramatically improved the stance and clearances. I have 18" rims and 33" tires. It also leveled the Jeep out, lifting the front a bit more than the back. I plan on a new front bumper and winch so the front will come back to neutral once I add more weight up front. Very satisfied with the JKS products. The Fox shocks that came with the kit are a bit stiff and I may invest in a set of the new Falcon adjustable shocks if my wife complains too much about the new stiffer feel of the Jeep on road.

Total extra weight 500Lbs . Pic is running 285 70 R17 Duratracs, aka 33s. After 30 days from install, still 3.5 inches up front and 2.5 inches in rear. Runs well on and off the trails.

      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.

      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.
