Locate and guide the front wheel with the Mevotech Supreme control arm, part number CMS861100 — a front left upper control arm and ball joint assembly that installs as a direct-fit replacement for the 1990-1994 Lexus LS400. The pivoting arm and integrated ball joint position the wheel and allow suspension travel; a worn unit can show up as clunking over bumps or during braking, loose or wandering steering, and uneven front tire wear.

  • Cast steel construction: built to OE-level fit and strength.
  • Quick installation: ships with the part-specific castle nut and cotter pin to secure the ball joint to the vehicle.
  • Corrosion resistance: a protective surface treatment helps resist rust build-up.
  • Rigorously tested: extensive in-house and third-party durability testing.

Because it serves as the front upper arm on the LS400, this piece also helps set front camber, so it doubles as the LS400 camber arm many owners search for. Whether you shop it as an LS400 upper control arm or a Mevotech Supreme suspension control arm, it's engineered for high-usage passenger vehicles and fleets.
