Locate the front wheel and support steering geometry with the Mevotech Supreme control arm CMS86180, a direct-fit front right lower forward control arm for the 2001-2005 Lexus IS300. This control arm links the steering knuckle to the chassis, positions the wheel, and pivots on its bushings to allow suspension travel while a worn original can let steering wander and produce clunks over bumps.
Engineered for high-usage passenger vehicles, SUVs, fleets and working trucks, this suspension control arm installs in the front right lower forward position. It is sold as a single arm for that specific position; the opposite side is a separate part. As an IS300 lower control arm it addresses signs like loose or wandering steering, clunking, and uneven tire wear when the original arm or its bushings are worn. See the Buyer's Guide tab for engine coverage.
