Rock Krawler 3.5in Adventure X Coil Over Lift Kit

The Rock Krawler Suspension JL 3.5 inch Adventure - X Mid-Arm System is specifically designed for Sport and Sahara owners who want a complete system, bolt-in installation, and the best articulation of any MID-ARM kit on the market. Our system proves its durability and off-road performance every time you hits the streets or trail! The Term, Adventure - X comes from the inclusion of 8 adjustable control arms with our 100% Service Free Adventure Series joints installed. Our industry leading, Adventure - X mid-Arms feature adjustable upper and lower control arms and offer a total of 70 degrees of misalignment when paired with our Adventure series Joints at the frame connection and at the axle. The inherent bind in a factory JL control arm is greatly reduced. With so much adjustability, it allows you to precision tune the JL's caster and pinion angle front and rear. Driving you home with the most comfortable ride possible in a Wrangler, are our TRIPLE RATE coils. All 4 coils work together to achieve excellent on-road comfort that we feel is better than the OEM linear rate springs. The coil itself is built with the proper "Free-length" for off-road articulation and stays firmly seated in the coil bucket (as long as a proper length shock is installed), and overall a very controlled reaction to bumps, rocks, sand, mud and whatever else you can manage to throw at them! All Rock Krawler JL systems include correction pads that reduce the spring bow inherent in the factory set up. The provided track bar geometry corrections, both front and rear, lets you perfectly center the axles so there is no compromise in on road handling.

 General Notes:

All lift heights based on Rubicon models for standard style build (i.e. front bumper and winch, rear bumper and full size spare).

XR Package does not require OUR raised rear track bar bracket, the factory axle has a raised rear trackbar bracket, and for OUR systems that do not have a rear trackbar one must be added.

If building with a spare delete we recommend dropping 1in in coil lift height for the rear.

If building an overland or heavily up-fitted build in the back, we recommend upsizing 1in in coil lift height for the rear.

We recommend a new front driveshaft if you plan to off-road routinely.(Adam's Drivesahft,Tom Woods,J.E. Reel)
