Keep your front wheel located and tracking true with the Mevotech Supreme control arm (CMS861132), a front left lower suspension control arm that anchors the steering knuckle to the chassis, pivots through suspension travel, and carries an integrated ball joint. It installs as a direct-fit replacement for the 2006-2015 Lexus IS250, 2016-2021 IS300, 2011-2021 IS350, 2006 GS300, and 2007-2011 GS350 — see the Buyer's Guide tab for engine-level fitment.
- Cast aluminum construction: built to OE-level tolerances for the listed applications.
- Longer ball joint life: an added surface treatment on the ball joint helps resist rust build-up.
- Premium materials: used across the components for longer part life.
- Tested for durability: validated by in-house and third-party durability testing, with Labor Saver designs and hardware to speed installation.
The lower control arm sets front wheel alignment and absorbs road inputs, so a worn arm or ball joint can show up as clunking over bumps, wandering steering, uneven tire wear, or alignment that won't hold. If a failed control arm is the cause, this Mevotech Supreme IS300 lower control arm replaces it. It's sold individually for the front left corner; for balanced handling, inspect the opposite-side arm and replace both as a matched set if worn.
