Description
The Rock Krawler JL 4.5 X Factor System is the ultimate JL Long Arm system for hard core rock crawling. 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 X Factor systems feature Independent 3 link designs front & rear for maximum articulation and off-road performance.
The rear suspension provides adjustable anti-squat 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” 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 high clearance long arms and 3 link suspension geometry lets you dominate the trails.
