ACDelco Professional Rear Lower Rearward Suspension Control Arm

The ACDelco Professional Rear Lower Rearward Suspension Control Arm is a replacement suspension control arm (also called a trailing arm or lateral link) that helps keep the rear wheel in correct alignment. It connects the axle or knuckle assembly to the vehicle's frame or subframe. It also controls wheel movement through suspension travel, which supports stable handling, ride comfort, and even tire wear.
