Restore tight, controlled steering and precise wheel location with the Mevotech Supreme control arm CMS501180, a front right lower control arm and ball joint assembly engineered for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks. It drops in as a direct-fit replacement for the 2011-2019 Chevrolet Silverado 2500 HD, 2011-2019 Chevrolet Silverado 3500 HD, 2011-2019 GMC Sierra 2500 HD and 2011-2019 GMC Sierra 3500 HD.
As part of the front lower suspension, this Mevotech Supreme suspension control arm locates the wheel and pivots as the suspension travels and steers, with the integrated ball joint handling both steering motion and load. If a worn ball joint or tired bushings are behind knocking over bumps, loose or wandering steering, or uneven tire wear, replacing this lower control arm assembly addresses those signs. This is the front right (passenger-side) unit; for balanced handling, consider replacing the opposite side at the same time.

Which position is this control arm?
It's the front right (passenger-side) lower control arm. For balanced handling, many technicians replace the left side at the same time.
Does it include a grease fitting and hardware?
Yes—it includes a 180-degree SAE grease fitting for servicing and a part-specific locking nut to speed up ball joint installation.
What is this control arm made of?
It uses cast steel construction with a protective surface treatment that resists rust build-up, plus sintered bearings for longer-lasting performance.
What are the signs I may need a new control arm?
Knocking over bumps, loose or wandering steering, and uneven front tire wear can point to a worn ball joint or bushings. Diagnose the cause first; if this assembly is worn, it replaces it.
