Dorman Cast Iron Control Arm

The Dorman cast iron control arm line offers suspension control arms (also called suspension arms or lower and upper control arms) built to restore the strength and ride quality of the original suspension. A control arm links the vehicle's chassis to the steering knuckle or wheel hub. It lets the wheel move up and down with the road while holding its position, which helps keep steering and handling stable.

Key Features:

• Cast iron construction for strength and durability under daily driving loads
• Designed to replace worn or damaged control arms and restore proper suspension geometry
• Helps return steering response, alignment stability, and ride comfort to original-equipment levels
• Built for direct replacement, which keeps installation straightforward
• Backed by Dorman's long experience in aftermarket replacement parts for vehicle repair

Worn control arms can cause clunking noises, uneven tire wear, vibration, and wandering steering. Replacing them helps restore safe, predictable handling. A professional alignment is recommended after installation. Pick the specific variant you need from the options on this page.
