Rock Krawler JL45X2PLA-2CS 4.5 Inch X-Factor X2 PRO Long Arm Coilover Comp Suspension Lift System

The Rock Krawler 4.5" X-Factor X2 PRO Long Arm Coilover Comp Suspension System delivers a purpose-built lift solution engineered for serious off-road performance without sacrificing on-road drivability. This Comp System configuration pairs front coilover racing shocks with a coil spring and shock combination in the rear, giving you race-inspired tunability up front while maintaining load-carrying capability in the rear.

At the heart of the X2 PRO system is Rock Krawler's independent 3-link long arm design front and rear, engineered for maximum axle articulation and improved suspension geometry over factory setups. The PRO designation means the lower control arms are CNC machined in-house from solid billet aluminum square stock — built to handle serious trail abuse while remaining completely service-free at the frame-side joints.
