The Rock Krawler Suspension JLU Wrangler 4.5 inch Adventure - X2 Long-Arm System is the ultimate in compromise between daily driver/hard core off-roader. The Adventure-X2 systems combine the benefits of a full high clearance 4 link front suspension with a high clearance independent 3 link rear suspension. Say goodbye to greasing your joints, our service free longarm system is here to stay. In every single control arm, we have our Adventure series joint center, which isolates harsh road vibrations equivalent to an OE bushing, includes high misalignment, and is fitted with a steel sleeve (that the bolt passes through) which rotates freely on a additional Teflon lined inner sleeve to insure that you are never chafing, twisting, or deforming the bushing material inside the housing as you blast through the mud, sand, sleet, salt, snow, dirt and dust. To finish it off, as you tighten your control arms into the mounts, the sleeve of the joint is engineered to be the buffer between the clamping force of a bracket, which means that as you tighten everything, you are not compressing the bushing. This all makes for an incredibly long lasting joint that never requires a drop of grease, and makes zero noise inside the housing. This is where conventional on road handling meets bad ass off-road ability. With enhanced rear instant center(s) and rear roll center(s), X2 rear suspension geometry is the smoothest riding 3-Link suspension you can take down a trail or cruise across America in your Wrangler. The new high clearance axle mounts provide 4.5” 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.
When we design a system, our 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

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 1” in coil lift height for the rear.
- If building an overland or heavily upfitted build in the back, we recommend upsizing 1” 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
- Recommend installing limiting straps to avoid over extension of suspension components after vehicle is all set up
