Locate the front right wheel and let it steer and travel smoothly with the Mevotech Supreme control arm (CMS861137), a front right upper control arm engineered in-house for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks. It drops in as a direct-fit replacement for the 2006-2015 Lexus IS250, 2006-2021 Lexus IS350, 2008-2014 Lexus IS F, 2016-2017 Lexus IS200T and 2018-2021 Lexus IS300 — see the Buyer's Guide tab for engine-level fitment.
- Quick, easy installation: secures the ball joint to the vehicle with the part-specific slotted castle nut and snap cotter pin provided.
- Stamped steel construction: built to OE-level tolerances for high durability.
- Resists corrosion: a protective surface treatment helps prevent rust build-up.
- Rigorously tested: validated by extensive in-house and third-party durability testing.
As the IS300 upper control arm, it positions the wheel while the integrated ball joint lets the suspension articulate and the wheel steer. Worn bushings or a loose ball joint on an IS300 control arm can show up as clunking over bumps, wandering steering, or uneven front tire wear — if a failed arm is the cause, this Labor Saver unit replaces it. Replace the matching side as directed by the service procedure for balanced handling.
