Rock Krawler JL45X2PNL-2CS 4.5 Inch X Factor X2 Pro No Limits Long Arm Coilover Suspension System

The Rock Krawler JL45X2PNL-2CS is the 4.5-inch X Factor X2 Pro "No Limits" Long Arm Coilover Suspension System — a hardcore rock crawling lift kit built for serious off-road performance. Featuring a front coilover setup paired with a comprehensive long arm conversion, this system delivers maximum articulation and trail capability while maintaining composed on-road handling.

The "No Limits" designation comes from the inclusion of specially engineered front sway bar links designed to work seamlessly with the factory electronic sway bar disconnect feature found on Rubicon models. With factory-sized hardware, a CNC-machined billet aluminum center section, and USA-made FK Bearing heim joints, Rubicon owners simply press the button and hit the rocks without sacrificing full articulation.

The X Factor X2 Long Arm System features an independent 3-link design front and rear for maximum suspension articulation and off-road performance. The proprietary double-adjustable front and rear upper control arms upsize factory hardware to 14mm with a 2-3/8" mounting width and 1" Pro Krawler joints at each end. The arms themselves are constructed from chromoly solid steel, engineered to handle the full forces of the suspension under extreme conditions.
