Locate the front wheel and manage suspension geometry with the Mevotech Supreme control arm CMS861321, a front left lower control arm and ball joint assembly engineered in-house with application-specific upgrades for high-usage commercial vehicles, passenger cars, SUVs and fleets. It's a direct-fit replacement for the 2020-2025 Toyota Highlander and 2023-2025 Lexus RX350, RX350H and RX500H, plus 2024-2025 Lexus RX450H+, TX350, TX500H and TX550H+ — see the Buyer's Guide tab for the full list.
- Complete solution: ships with the ball joint pre-assembled to the arm for faster installation.
- Stamped steel construction: a structure change adds durability for demanding use.
- Sintered bearings: built for longer-lasting performance.
- Double-bonded bushings: upgraded for increased stiffness and durability to help handling.
- Serviceable: includes a 135-degree SAE grease fitting.
- Hardware included: a part-specific castle nut and cotter pin secure the ball joint to the vehicle.
A protective surface treatment resists rust build-up. As the lower control arm on the front left (driver's) corner, it locates the wheel and, through its ball joint and bushings, allows controlled suspension movement — worn bushings or a loose ball joint can produce clunks, wandering steering and uneven tire wear.
