For the Ultimate Short Arm lift, Rock Krawler Suspension has produced the X-Factor Series. X-Factor Systems are the highest performing kits on the market today made with best materials available. Included in all X-Factor Systems are completely adjustable upper and lower control arms, track bars, and sway bar end links. X-Factor Lift kits also push your rear axle back 1Β to properly center the axle in the vehicles wheel opening. You can either purchase shocks separately, or you can select one of Rock Krawler's proven RRD 2.0 Prodigy shock options.
