$75.99

Tighten up front-end steering and articulation with the Mevotech Supreme control arm and ball joint assembly (CMS86177). This unit installs as the front left (driver's side) upper control arm and drops in as a direct-fit replacement for the 2001-2005 Lexus IS300, locating the wheel while its integrated ball joint allows the suspension and steering to pivot.

  • Quick, easy installation: secures to the vehicle with the part-specific slotted castle nut and easy-snap cotter pin provided.
  • Stamped steel construction: built to OE-level tolerances for the load of high-usage passenger vehicles, SUVs and working trucks.
  • Resists corrosion: a protective surface treatment helps limit rust build-up for longer part life.
  • Rigorously tested: extensive in-house and third-party durability testing validates strength and performance.

A worn IS300 control arm or its ball joint can show up as clunking over bumps, steering wander, looseness or uneven tire wear. If a failed upper control arm or ball joint is the cause, this assembly replaces both in one part. Application-specific Mevotech Supreme engineering adds Labor Saver™ hardware to speed the job.
