Locate the rear wheel with confidence using the Mevotech Supreme control arm (CMS861287), a rear right upper control arm and ball joint assembly that positions the wheel, allows suspension travel, and lets its integrated ball joint articulate as the suspension moves. It drops in as a direct-fit replacement for the 1998-2005 Lexus GS300, the 1998-2000 Lexus GS400, and the 2001-2005 Lexus GS430 — see the Buyer's Guide tab for engine-level fitment.
- Application-specific engineering: Designed in-house with targeted upgrades aimed at added durability for high-use passenger vehicles, SUVs, fleets and working trucks.
- Hardware included: Ships with the part-specific castle nut and cotter pin to secure the ball joint to the vehicle for a quicker install.
- Corrosion-resistant ball joint: An added surface treatment helps prevent rust build-up for longer ball joint life.
- Knurled bushing fit: Added knurling locks the control arm bushing to the sub-frame for a secure, optimal fit.
- Cast aluminum construction: Built to meet or exceed OE specifications.
Clunking over bumps, loose or wandering steering, or uneven tire wear can be signs the original control arm bushing or ball joint is worn. If a worn arm or joint is the cause, this assembly replaces both in one unit. For balanced handling, inspect the matching side and replace fasteners as directed by the service procedure.
