3.5 Inch Adventure-X "No Limits" Long Arm Suspension - 2 Door JL 392

The Rock Krawler 3.5 Adventure-X System is the ultimate in compromise between daily driver/hard core off-roader AND is now specifically designed for the the 392 Platform. We achieve this by adding 392 specific Triple Rate Coil springs that achieve 3.5 inches of lift height over the FACTORY 1" lift height. What this means: The springs are a heavier rate to account for the massive 392 cubic inch, V8 engine and give you a ride height that achieves a balanced, functional lift system. The Rock Krawler No Limits systems feature our No limits front sway bar links that allow Rubicon owners to utilize the factory Rubicon sway bar disconnect feature and still achieve full articulation. The Adventure-X systems combine the benefits of a full high clearance 4 link front suspension with a high clearance independent 3 link rear suspension. This is where conventional on road handling meets bad a$$ off-road ability. The rear system uses our tried and true independent 3 link conversion with X2 rear suspension geometry with enhanced rear instant center(s) and rear roll center(s). The new high clearance axle mounts provide 4.5 inches of ground clearance under the rear axle as compared to stock. The rear upper shock relocation brackets ensure you do not lose any shock or suspension travel. The combination of a full high clearance 4 link long arm front suspension and high clearance independent 3 link rear long arm suspension lets you dominate the streets and the trails.

General Notes:

*All lift heights based on Rubicon 392 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 1Ó in coil lift height for the rear.

*If building an overland or heavily upfitted build in the back, we recommend upsizing 1Ó in coil lift height for the rear.

*Recommend a new front C.V. driveshaft for all front shocks with max. extended length greater than 29"

*Requires welding of the Front and Rear Long Arm Mounts

*Requires removal of the OEM frame side lower front and rear control arm mounts

*Requires removal of the OEM frame side front and rear upper control arm mounts

*Requires removal of the OEM axle side rear lower control arm and track bar mounts

*Requires modifying the OEM rear shock mounts and welding of the raised rear upper shock mounts
