ACDelco Professional Upper Control Arm Ball Joint Assembly

The ACDelco Professional Upper Control Arm Ball Joint Assembly is a suspension ball joint that connects the upper control arm to the steering knuckle. It lets the wheel pivot and move with the suspension, which helps keep steering precise and the ride stable. It is sold as a replacement upper ball joint, and you may also see it called an upper control arm ball joint or suspension ball joint.

Key Features:

• Professional line from ACDelco, a brand with a long history of supplying GM and aftermarket replacement parts
