Rock Krawler 4.5in Adventure-X Coil Over Long Arm Lift Kit

The Rock Krawler JK 4.5 Adventure-X Coil Over Systems is the ultimate in compromise between daily driver/hard core off-roader. 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 ass 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 3.5” 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.

System Benefits

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).

*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.

*Requires removal of many OEM brackets both at the frame and axles. See instructions for details.

*Requires welding of many Rock Krawler brackets both at the frame and axle. See instructions for details.

*Minor exhaust rerouting required before the collector on the driver's side to be done prior to the suspension system install.

*Recommend installation of limiting straps to avoid over extension of suspension components.

*This system pushes the rear axle back approximately 1”, to center the rear axle assembly and prevent larger tire from contacting the rock sliders and pinch seam.

*System designed for low pinion axles. Contact Rock Krawler for high pinion options.

*Recommend 4.5” of back spacing on rims for 33” and 35” tall tires.

*Recommend 3.5” of back spacing on rims for 37” tall tires.
