The Rock Krawler Suspension JT 3.0 inch ADVENTURE - X “NO-LIMITS" Mid-Arm System is specifically designed for Rubicon owners who want a complete system, bolt-in installation, and some of the best articulation of any MID-ARM kit on the market. This system proves its durability and off-road performance every time you hit the streets or trail! "No-Limits" comes from the inclusion of our front sway bar links specifically designed for use with the factory electronic sway bar disconnect feature found standard in your Rubicon Gladiator! The sway bar links come with factory-sized hardware, a CNC machined billet aluminum center section, and Made in USA Heim joints from the FK bearing; once installed, press the button and hit the rocks! The Term, Adventure - X comes from the inclusion of 8 adjustable control arms with our 100% Service Adventure Series joints installed.

The industry-leading, Adventure - X mid-Arms feature adjustable upper and lower control arms and offer 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, 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 (if 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, both front and rear, 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)
