The Rock Krawler Suspension JT 3.0-inch ADVENTURE - X PRO Mid-Arm System is specifically designed for Sport, Mojave, and Overland owners who want a complete system, bolt-in installation, and some of the best articulation of any MID-ARM kit on the market. Our system proves its durability and off-road performance every time you hit the streets or trail! The Term, Adventure - X includes 8 adjustable control arms with our 100% Service Adventure Series joints installed. The kit becomes the "PRO" version due to our rear Bolt-in triangulated upper control arms. The triangulated 4-link rear assembly keeps the rear axle perfectly centered, allows for the removal of the rear track bar, and eliminates rear suspension bind and the cross-talk of the front and rear track bar arrangement, therefore greatly smoothing the highway ride. 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 the axle.
The inherent bind in a factory JL/JT control arm is greatly reduced. With so much adjustability, it allows you to precision-tune the JT's caster and pinion angle front and rear. Driving you home with the most comfortable ride possible in a Gladiator is the TRIPLE RATE front coils and QUAD RATE rear coils. All four coils work together to achieve excellent on-road comfort that we feel is better than the OEM springs. The coil is built with the proper "Free-length" for off-road articulation. It stays firmly seated in the coil bucket (as long as a proper length shock is installed), and overall, it is a very controlled reaction to bumps, rocks, sand, mud, and whatever else you can throw at them! All Rock Krawler JT systems include correction pads that reduce the spring bow inherent in the factory setup. The provided track bar geometry corrections up front and removal of it in the rear in favor of triangulation lets you perfectly center the axles, so there is no compromise on road handling.

General Notes:
All lift heights are based on Rubicon models for standard style build (i.e., front bumper and winch, rear bumper, and full-size spare).
If building with a spare delete, we recommend dropping 1” in coil lift height for the rear. If building an "overland style" or heavily up-fitted build in the back, we recommend upsizing 1” in coil lift height for the rear.
We recommend a new front driveshaft if you plan to off-road routinely. (Adam's Driveshaft, Tom Woods, J.E. Reel) Requires removal of the OEM shock mount off the frame (*If coilover system is purchased)
Requires removal of the OEM shock and spring mount off the axle (*If coilover system is purchased) Requires welding of the new coil over the mount on the axle only (*If coilover system is purchased)
We recommend welding the rear cradle with 37" tires and above.
