Keep your front suspension precisely located with the Mevotech Supreme control arm and ball joint assembly (MPN CMS86178), a direct-fit replacement for the front right upper position on the 2001-2005 Lexus IS300. This one-piece unit combines the upper arm with its integrated ball joint, so it locates the wheel, allows suspension travel, and lets the knuckle pivot for steering.
- Quick installation: secure the ball joint to the vehicle with the part-specific slotted castle nut and snap cotter pin provided.
- Stamped steel construction: built to meet or exceed OE specifications.
- Resists corrosion: a protective surface treatment helps prevent rust build-up and extend part life.
- Rigorous testing: extensive in-house and third-party durability testing.
Engineered in-house with application-specific upgrades, the Mevotech Supreme line is built for high-usage passenger vehicles, SUVs, fleets and working trucks, with Labor Saver hardware to speed the job. As an IS300 upper control arm, worn ball joints or bushings can bring on clunking over bumps, loose or wandering steering, and uneven tire wear. If a worn IS300 control arm is the cause, this assembly replaces the arm, ball joint and bushings in a single install.
