The Rock Krawler JL35X2PNL-392TR is a 3.5-inch X-Factor X2 Pro No Limits Trail Runner Long-Arm Suspension System purpose-built for the Jeep Wrangler JL platform with the 392 cubic inch V8 engine. This system represents the pinnacle of Rock Krawler's long-arm engineering, combining hardcore off-road capability with street-friendly daily drivability.
The "No Limits" designation reflects the inclusion of specially engineered front sway bar links designed to work seamlessly with the factory electronic sway bar disconnect feature found on Rubicon models. With factory-sized hardware, a CNC machined billet aluminum center section, and USA-made FK Bearing heim joints, simply press the button and hit the rocks.
At the heart of this system is Rock Krawler's proven X-Factor X2 Independent 3-Link geometry, front and rear, delivering maximum suspension articulation and off-road performance. The double adjustable front and rear upper control arms upsize factory hardware to 14mm with 2-3/8" mounting width and 1" Pro Krawler joints at each end. The chromoly solid steel lower arms are engineered to handle the full forces of the suspension under extreme use.
The "PRO" designation brings Rock Krawler's Adventure Series maintenance-free joints at the frame-side connections of the lower control arms, eliminating grease points while providing excellent vibration absorption and proper misalignment capability on the trail. The rear X2 geometry delivers adjustable anti-squat with enhanced rear instant centers and roll centers for optimized handling on and off road.
The Trail Runner package adds a coilover shock system for an additional level of tunability, allowing owners to dial in ride quality, handling, and off-road performance to their preference. The system also includes 392-specific Triple Rate Coil Springs — tuned with a heavier spring rate to properly support the weight of the 6.4L HEMI V8 while achieving a full 3.5 inches of usable lift height over the factory 1-inch raised ride height.
