The Rock Krawler JL45X2PNL-2S1 is a 4.5-inch X Factor X2 Pro "No Limits" Long Arm Suspension System built for hardcore rock crawling on the Jeep Wrangler JL 2-Door. This Stage 1 long-arm lift kit combines a full high-clearance 4-link front suspension with a high-clearance independent 3-link rear suspension for maximum articulation and off-road dominance.
The "No Limits" designation means this system includes purpose-built front sway bar links engineered to work seamlessly with the factory electronic sway bar disconnect feature found on Rubicon models. The sway bar links feature factory-sized hardware, a CNC machined billet aluminum center section, and Made-in-USA heim joints from FK Bearing — just press the button and hit the rocks.
The "X2 Pro" architecture utilizes a proprietary double-adjustable front and rear upper control arm, upsizing factory hardware to 14mm with a 2-3/8-inch mounting width and 1-inch Pro Krawler joints at each end. The chromoly solid steel arm is engineered to carry all suspension forces under extreme loads. The rear suspension delivers adjustable anti-squat with X2 geometry featuring enhanced rear instant centers and rear roll centers. New high-clearance axle mounts add 4.5 inches of ground clearance under the rear axle versus stock, and rear upper shock relocation brackets ensure no shock or suspension travel is lost.
