Our 3.5 X-Factor Plus Short Arm system allows you to run up to 33" tires with excellent road manners and unparalleled off-road ability. Our rebuildable spherical Krawler Joints at the axle connections allow for a tremendous amount of twist. The rear features our triangulated 4 link conversion allowing removal of the rear track bar for maximum rear axle articulation. The Rock Krawler LJ X-Factor Plus system was designed with anti-squat geometry for improved vertical climbing ability. We use a rear upper reinforcing mounts to improve the strength of the OEM rear upper control arm brackets. The weld on rear cradle improves the overall strength of the factory rear axle housing and provides mounting points for the triangulated 4 link members.
