Rock Krawler 4.5in X Factor X2 Long Arm Lift Kit
JL Diesel
Features & Product Details
The Rock Krawler JL 4.5 X Factor X2 Systems is the ultimate JL Long Arm system. The X Factor systems feature 3 link set-up front & rear for maximum articulation and off-road performance. The rear suspension provides the tried and true independent 3 link conversion with X2 rear suspension geometry. New high clearance axle mounts provide 4.5” of ground clearance under the rear axle as compared to stock. Rear upper shock relocation brackets ensure you do not lose any shock travel. The combination of high clearance mounting and 3 link suspension geometry lets you dominate the trails.

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 the use of Steersmarts XD Yeti HD Bottom Mount Drag Link for Off-Road Use
*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 Mount
*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
