      5 Top Rated Questions

      If I purchase this lift kit, do I need to purchase anything else or make any modifications to the jeep? I was once told that any lift kit bigger than 3 in required modifications to the drive shaft. What about the exhaust spacer, is it required?

      • The JKS Jspec 3.5 in. Lift Kit (07-17 Wrangler JK 4-Door) would be a pretty complete kit. If you are using the Jeep primarily for off roading I will then recommend a longer driveshaft, to gain the full articulation of the suspension. For a daily driven Jeep, an exhaust spacer will do just fine.

      With a heavy front bumper and winch..how much sag will the front end have..how long are the spring warranty..thank you

      • Hello! How much your Wrangler sags is dependent on many factors, so it is hard to say, however most of these springs are built in mind that people will be putting heavy aftermarket bumpers on! JKS has a limited lifetime warranty!

      Will this lift fit my 2015 JKU? What other items are needed for daily drive and moderate off-roading?

      • The JKS Jspec 3.5 in. Lift Kit will fit the 07-18 JKU Jeep Wranglers. Upgrading the front driveshaft would be advised and for the 2012+ JKU's exhaust spacers will be required.

      Will I need to buy a new front Driveshaft for my jeep? People are telling me that a stock driveshaft will only work on 2.5" and 3" kits?

      • Yes, a new front driveshaft would be required when installing this lift.

          Review from JKS JSPEC 3.5 in. Suspension Lift Kit w/ JSPEC Gas Shocks (07-18 Jeep Wrangler JK 2 Door)

          Great lift. Couldn't be happier!

          Great kit, comes with almost everything that you need. I only needed to add exhaust spacers and chose to get the Control Arm Relocation Brackets (JKS as well). Overall, kit was very straight forward to put in. Rides 100 times better than the stock springs/shocks.

          Great Lift Kit

          I have had no issues with this lift kit! Could have come with complete instructions, it was vague at times. The 3.5” sizing is great, I fit in most garages in my area.

          Great product

          Well built lift kit. Bought the lowest priced 3.5” kit and added front lower control arms, exhaust spacer kit and rear adjustable sway bar end links. In the future I will upgrade to adjustable upper and lower front/rear control arms. I have also purchased a teraflex high angle front drive shaft cv boot to replace the factory one when it eventually fails with future plans for new/stronger driveshafts. Did not have any major issues with install besides a rusted broken bolt when installing the exhaust spacers that gave me some trouble.

          The lift kit was in good shape with reasonably good direction. Fortunately my buddy had put one in a year ago and could get us through some bumpy spots in the directions. He also had two jacks and 4 fixed jacks. Makes a huge difference.

          Great Start

          If you're piecing together a kit, this is a great place to start. Similar ride to factory with added clearance on the trail. Front flexes it great. Not so much in the rear but quite certain the sway bar is hurting me there. Had to get new pin rings for the discos though.

          Just picked it up today, the ride is better than I expected. 33" Mickey Thompson Baja and still pretty smooth on the street. Glad I went with the 3.5 lift weights the this tire, so much clearance. Now to try it in the mud!

          Wish it had better step by step instructions. It had ok instructions but there was a lot of guessing. It would have been a lot easier if it had pictures for every step. Over all pretty satisfied with the life besides the instructions. Rides smooth with the 35’s I installed. Only reason it took the full day was because the hobby shop we used lacked tools.
