This Dorman lower control arm links the steering knuckle to the chassis. It lets the wheel travel up and down while holding it in position. The ball joint is the pivot point for steering and suspension movement, and the bushings cushion the arm at its mounting points.
- Direct replacement: This Dorman suspension control arm and ball joint assembly directly replaces the original assembly on the specified applications.
- Pre-installed components: The ball joint and bushings come already installed, which saves time and labor during the repair.
- Tested design: The arm went through Dorman's industry-leading evaluation process. It is designed for a smooth ride, directional stability and predictable handling.
