Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS501142
Keep the front suspension located and the ride controlled with the Mevotech Supreme control arm (CMS861129), a front right lower control arm and ball joint assembly that installs as a direct-fit replacement for the 2004-2009 Toyota Prius. The control arm locates the wheel and allows suspension travel, while the integrated ball joint lets the steering knuckle pivot for steering and ride motion — worn bushings or a loose ball joint can bring on clunking over bumps, uneven tire wear, and vague steering.
Engineered in-house with application-specific upgrades, this Mevotech Supreme lower control arm is built for high-usage passenger vehicles, SUVs, fleets and working trucks. Whether you're shopping for a Mevotech Supreme suspension control arm as routine maintenance or after a failed ball joint, it bolts in for the 2004-2009 Prius.
