Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS80105
Mevotech Supreme control arm CMS501179 combines the front left lower control arm and its integrated ball joint into one bolt-in assembly, engineered in-house with application-specific upgrades for increased durability. It drops in as a direct-fit replacement for many vehicles, among them the 2011-2019 Chevrolet Silverado 2500 HD, 2011-2019 Chevrolet Silverado 3500 HD and 2011-2019 GMC Sierra 2500 HD — see the Buyer's Guide tab for the full list and engine-level fitment.
This Mevotech Supreme lower control arm locates the front wheel and, with its pre-installed ball joint, controls suspension movement while letting the wheel steer and travel. Built for high-usage commercial and passenger vehicles, fleets and working trucks, this Mevotech Supreme suspension control arm helps restore proper wheel geometry. Clunking over bumps, wandering steering, or uneven front tire wear can be signs of a worn arm bushing or a loose ball joint — diagnose the cause before replacing.
