Rock Krawler JK35X2PLA-4 3.5 Inch X Factor X2 PRO Long-Arm Suspension Lift System 4-Door

The Rock Krawler JK35X2PLA-4 is a 3.5-inch X Factor X2 PRO Long-Arm Suspension System engineered for Jeep Wrangler JK 4-Door owners who demand the best in both daily-driver comfort and hardcore off-road performance. This complete long-arm lift kit delivers 3.5 inches of lift while transforming your JK's suspension geometry for maximum articulation, improved ground clearance, and a confident ride on any terrain.

The PRO designation means this system is equipped with billet aluminum CNC-machined lower control arms — custom machined in-house from solid square stock billet aluminum to handle any abuse thrown at them. These maintenance-free arms eliminate the need for regular greasing while delivering exceptional strength and durability.

At the heart of this system is Rock Krawler's proprietary X Factor X2 suspension geometry, which combines a full high-clearance independent 3-link front suspension with a high-clearance independent 3-link rear suspension. The double adjustable front and rear upper control arms upsize the factory hardware to 14mm with a 2-3/8-inch mounting width and 1-inch Pro Krawler joints at each end — built from chromoly solid steel to carry the full forces of the suspension.

The rear system features Rock Krawler's X2 geometry with enhanced instant centers and roll centers for improved handling both on and off-road. New high-clearance rear axle mounts provide 3.5 inches of additional ground clearance under the rear axle versus stock, while rear upper shock relocation brackets ensure no loss of shock travel or suspension articulation.
