Our rear upper control arms are a direct replacement for the factory arms and  are designed to minimize wheel hop, improve cornering and help track consistency.  This control arm is on-car adjustable and allows easy pinion angle adjustments.  Adjustments are made while the control arm stays attached to the vehicle.  Competitor designs require you to remove the control arm from the vehicle to  adjust. Adjustment can also be used to eliminate the use of shims during installation.
