The Rock Krawler 3.5 X Factor Systems is the ultimate JL Long Arm system. 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 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 long arms and 3 link suspension geometry lets you dominate the trails.
