Rock Krawler JL35X2PLA-2S1 3.5 Inch X Factor X2 Pro Long Arm Suspension System Stage 1

The Rock Krawler JL35X2PLA-2S1 is the 3.5-inch X Factor X2 Pro Long Arm Suspension System Stage 1 — a complete long-arm lift kit engineered for hardcore Jeep Wrangler JL owners who demand maximum off-road articulation without sacrificing street manners. This system delivers 3.5 inches of lift height and is purpose-built for serious rock crawling performance.

At the heart of this system is Rock Krawler's industry-leading independent 3-link design front and rear, providing maximum articulation and off-road performance. The proprietary double-adjustable front and rear upper control arm upsizes the factory hardware to 14mm with a 2-3/8-inch mounting width and 1-inch Pro Krawler joints at each end. The upper arm itself is a chromoly solid steel arm designed to carry all the forces of the suspension under extreme trail conditions.

The rear suspension utilizes X2 rear suspension geometry with enhanced rear instant centers and rear roll centers, delivering adjustable anti-squat so the system can be precisely tuned to your driving style. New high-clearance axle mounts provide 4.5 inches of additional ground clearance under the rear axle compared to stock, while rear upper shock relocation brackets ensure zero loss of shock travel.

Frame-side connections on the lower control arms use Rock Krawler's Adventure Series maintenance-free joints, reducing grease points and providing excellent vibration absorption with proper joint misalignment capability when off-road. Heat Shield thermal barrier protection is included for front control arm joints at the frame — just like OEM.
