Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS80105
Keep your front suspension precisely located and your steering responsive with the Mevotech Supreme Front Left Upper Control Arm and Ball Joint Assembly (CMS86134) — a direct-fit Tundra upper control arm for the 2007-2021 Toyota Tundra and 2008-2022 Toyota Sequoia. This front left upper unit connects the frame to the steering knuckle and pivots through suspension travel, while the integrated ball joint lets the knuckle swivel for steering and articulation.
Mevotech Supreme parts are engineered in-house with application-specific upgrades aimed at high-usage passenger vehicles, SUVs, fleets and working trucks.
This is the front left upper arm, sold individually; the right-side arm is a separate part, and replacing both sides together is good practice for balanced handling. If a worn control arm bushing or ball joint is behind clunking over bumps, steering wander, or uneven tire wear, this Mevotech Supreme control arm replaces it.
