Product Resources
Features & Product Details
The Rock Krawler JK 4.5 X Factor X2 Coil Over Systems is the ultimate JK Long Arm system for the trail. The X Factor systems feature 3 link rear 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 3.5” 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 mounts and 3 link suspension geometry lets you dominate 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.
*Requires rear long travel sway bar
