ACDelco Upper Control Arm Assembly

The ACDelco Upper Control Arm Assembly is a replacement suspension control arm built to restore ride quality, steering response and alignment stability. Upper control arms (also called upper A-arms) connect the vehicle's frame to the steering knuckle. They allow the wheel to move up and down with the road while holding its position.

Key Features:

• Assembly design that typically includes the control arm with pivot bushings and ball joint, which simplifies installation compared with replacing individual components
• Engineered to meet or exceed original equipment performance expectations
• Helps restore proper wheel alignment geometry and tire contact with the road
• Durable construction built to withstand road shock, load and wear
• Backed by the ACDelco brand, the original equipment parts brand of General Motors

Worn control arms, bushings or ball joints can cause clunking noises, vague steering, uneven tire wear and wandering at highway speed. Replacing the upper control arm assembly helps bring back smooth, controlled handling and a comfortable ride. A professional wheel alignment is recommended after installation.
