Rock Krawler JL35X2LA-4TR 3.5-Inch X-Factor X2 Trail Runner Long-Arm Suspension Lift Kit

The Rock Krawler JL35X2LA-4TR is a 3.5-inch X-Factor X2 Trail Runner Long-Arm Suspension System built for serious off-road performance. Engineered specifically for the Jeep Wrangler JL Unlimited (4-door), this long-arm lift kit delivers a complete suspension overhaul with Race-Ready coilover shocks and Rock Krawler's proven X2 suspension geometry — giving you maximum articulation on the trail without sacrificing on-road composure.

At the heart of this system is Rock Krawler's Independent 3-Link design front and rear, providing exceptional articulation and off-road capability. The proprietary double-adjustable front and rear upper control arms upgrade factory hardware to 14mm with 2-3/8" mounting width and 1" Pro Krawler joints at each end. Control arm tubes are constructed from chromoly solid steel designed to handle the full forces of the suspension under the most demanding conditions.
