      JKS needs more credit for how great they are....

      Had the 3.5" jSpec lift with FOX 2.0 res shocks and FOX steering dampener installed on my 2012 JK SPORT 2DR along with 35" BFG KM3. After much research i found the JKS kit to be the best on the market for my price range. THERE IS NO BETTER. As an engineer i looked each piece over and was pretty impressed with the design of it all. Very few things that i would personally change. Packaging was awesome. MY JEEP now rides like a caddie. I am so happy with the on road manors. Off-road is amazing. The quick disconnects are worth every penny. Everything is AMERICAN MADE!!!!

      drag link flip kit wore out knuckle in 7000 miles

      Most of the lift seems ok but the drag link flip is the weak link. Where they have you drill out has worn out in less than 7000 miles of use and I would never use again. Now I must replace my knuckles and drag link due to their terrible design.

      Amazing kit!

      Had a local shop do the install because it’s winter and I don’t work outside in the cold. But the difference is unbelievable! It lifted my Jeep close to five inches overall and the ride quality is far beyond what I expected. No bump steer, no rattles and it actually rides better than it did on the factory suspension. I’ll be buying this kit for my next jeep, too.

      Very Nice Kit

      What set this lift kit apart for me was the control arm relocation brackets. It made sense to keep the same geometry if possible and not add to the angles when lifting my Jeep. The front end alignment proved it works. Barely needed any adjustments at all. I did buy the adjustable sway bar links to avoid drilling holes in the stock rear brackets and I highly recommend that. It rides a little stiffer than stock but I didn't expect it to be a limo ride. The components seem quality and I'm very pleased with the outcome. Approx 8 hours on the install, solo.

      Worth for the money

      This is a good quality lift kit. It includes pretty much everything what u need. Make sure add a exhaust spacer. It took me almost 1 and a half days to install this kit with basic tools. I replaced the all 4 control arms with jks j spec. Over all I like this product.

    5 Top Rated Questions

    with this lift do I need a rear track bar? do I need new front and rear control arms? do I need a new steering stabilizer and do I need new front and rear drive shafts? I've never lifted any of my jeeps but I want to make sure I get it all done right and I don't want to buy thing I don't need!!

    • This lift kit will come with a rear track bar bracket, and control arms brackets and will not need any additional parts to get your Jeep safely lifted.

    Any drive train or other geometry issues that need to be corrected with parts not included with the 3.5 jspec lift kit?

    • With the JKS Jspec 3.5 in. JKontrol Lift Kit the only additional parts that JKS recommends are a steering stabilizer and exhaust spacers. The spacers are for 3.6L model Jeeps only. Every Jeep reacts differently to being lifted and you may find that at 3.5" your stock driveshafts are overextended and you need to go to aftermarket ones rated for your lift height.

    Is this product made in China?

    • JKS manufactures all of their products in the US in their facility in Michigan.

    Will this kit level out the factory rake or would an additional spacer in the front be recommended?

    • The JKS Jspec 3.5 in. JKontrol Lift Kit will eliminate the factory rake and level out a majority of the vehicle when properly installed. No additional accessories will be needed to level out the vehicle outside of this lift kit.

    What difference does the JKontrol make?

    • The J Kontrol system contains JKS’s beefy control arm relocation brackets with an OEM style drag link flip kit for the ultimate combination of durability, road comfort and un-rivaled street handling. The control arm bracket flattens the front control arm angles and correct alignment. The drag link flip kit levels the drag link which completely eliminates any hint of bump steer.
