The Rock Krawler 3.5" Ultimate Adventure Mid-Arm 392 System is specifically designed for Wrangler owners who want a complete system, bolt-in installation, and some of the best articulation of any MID-ARM kit on the market. The Term, "No-Limits" comes from the inclusion of the front sway bar links specifically designed for use with the factory electronic sway bar disconnect feature found standard in your Rubicon Wrangler! The sway bar links themselves come with factory sized hardware, a CNC machined billet aluminum center section, and Made in USA heim joints from FK bearing, once installed, just press the button and hit the rocks! This system proves its durability and off-road performance every time you hit the streets or trail! The Term, "Ultimate Adventure System" comes from the inclusion of 4 non-adjustable Lower control and 4 fully adjustable upper arms with the 100% Service Free Adventure Series joints installed. Rock Krawler's industry leading, Adventure series mid-Arms, offer a total of 70 degrees of misalignment when paired with the Adventure series Joints at the frame connection and at the axle. The inherent bind in a factory JLU control arm is greatly reduced.

Driving you home with the most comfortable ride possible in a Wrangler are the 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 JLU 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, let you perfectly center the axles so there is no compromise in on road handling. When Rock Krawler design a system, their goal is to provide you with the most comprehensive solution and the best geometry, install exceptional value, and be the foundation for every adventure whether it be on the Street, In tow, or down a Trail! Thank you for considering Rock Krawler Suspension.

Rubicon Fitment Recommendations

37” Tall Tires – Recommend 4.5” of Back Spacing
40" Tall Tires – Recommend 3.5” of Back Spacing

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 Rock Krawler's raised rear track bar bracket, the factory axle has a raised rear trackbar bracket, and for their systems that do not have a rear trackbar one must be added.
• If building with a spare delete, we recommend dropping 1” in coil lift height for the rear.
• If building an overland 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)
