ACDelco Front Upper Suspension Control Arm and Ball Joint Assembly

The ACDelco Front Upper Suspension Control Arm and Ball Joint Assembly is a front upper control arm with a ball joint already installed. It is also called an upper control arm with ball joint or an A-arm assembly. The control arm links the steering knuckle to the vehicle frame. It helps keep the wheel aligned and lets the suspension move up and down.

Key Features:

• Control arm and ball joint come as one assembly, so you don't have to press a ball joint into the arm separately
• Built to work as a replacement for the original suspension component
• Helps restore steering response, ride quality, and wheel alignment stability
• Backed by ACDelco, the GM parts brand with a long history in original equipment and aftermarket replacement parts
• Suited to replacing worn, noisy, or damaged control arms and ball joints

Replacing a worn control arm or ball joint can reduce clunking, vague steering, and uneven tire wear. A wheel alignment is recommended after installation. Choose the specific part number in this product line for your application.
