Description

UMI Performance offers an on-car adjustable control arm for the rear of the GM B-Body vehicle. This control arm is a direct replacement for the factory arms and helps minimize wheel hop and improve cornering. It allows for easy pinion angle adjustments without the need to remove it from the vehicle. The control arm features grease-able bushings, TIG welded construction, and a 4140 heat treated CrMo adjuster. This item is sold individually, so please verify how many you need for your vehicle.
