The Rock Krawler JL35X2PNL-4TR is a 3.5-inch X-Factor X2 Pro "No Limits" Trail Runner Long-Arm Suspension System purpose-built for hardcore rock crawling and off-road performance. The Trail Runner configuration features front and rear coilover shocks at all four corners, maximizing suspension travel and off-road capability while delivering a well-tuned street ride.
The "No Limits" designation comes from the inclusion of specially engineered front sway bar links compatible with the factory electronic sway bar disconnect. These links feature factory-sized hardware, a CNC-machined billet aluminum center section, and American-made FK Bearing heim joints — allowing Rubicon owners to use the OEM disconnect button and achieve full suspension articulation on the trail.
At the heart of the system is Rock Krawler's proven Independent 3-Link front and rear suspension geometry, delivering maximum articulation and off-road performance. The proprietary double-adjustable upper control arms upsize factory hardware to 14mm with a 2-3/8-inch mounting width and 1-inch Pro Krawler joints at each end. The arms themselves are chromoly solid steel, engineered to handle the full forces of the suspension system.
The rear suspension uses Rock Krawler's X2 geometry, featuring enhanced rear instant centers and rear roll centers for improved stability. High-clearance X2 axle bracket mounts deliver up to 4.5 inches of additional ground clearance under the rear axle versus stock. Rear upper shock relocation brackets ensure no loss of shock or suspension travel.
