Rock Krawler JL45X2PNL-4DS1 4.5-Inch X Factor X2 Pro No Limits Long Arm Suspension Kit Stage 1

The Rock Krawler JL45X2PNL-4DS1 is a 4.5-inch X Factor X2 Pro "No Limits" Long Arm Suspension System — Stage 1, engineered for serious off-road performance. This complete front and rear long arm lift kit is purpose-built for hardcore rock crawling while maintaining composure on daily-driven roads.

The "No Limits" designation refers to the inclusion of specially designed front sway bar links that allow Rubicon owners to fully utilize the factory electronic sway bar disconnect feature and still achieve maximum articulation on the trail.

The X Factor X2 system features an independent 3-link design front and rear for maximum articulation and off-road performance. The proprietary upper control arm design upsizes factory hardware to 14mm with a 2-3/8" mounting width and 1" Pro Krawler joints at each end, built from chromoly solid steel to handle the full forces of the suspension. The rear suspension delivers adjustable anti-squat with X2 geometry featuring enhanced rear instant centers and rear roll centers for a smooth, controlled ride on any terrain.
