Keep your Lexus tracking straight with the Mevotech Supreme control arm (CMS861243), a direct-fit front left lower (rearward) replacement for the 1998-2005 Lexus GS300, 1998-2000 Lexus GS400 and 2001-2005 Lexus GS430. This suspension control arm links the front wheel to the chassis, locating the wheel and allowing the suspension to travel while holding your alignment settings.

  • Forged steel construction: built to OE-level tolerances for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks.
  • Resists corrosion: a protective surface treatment guards against rust build-up.
  • Labor Saver™ design: innovative designs, tools and hardware speed up installation.
  • Rigorously tested: extensive in-house and third-party durability testing backs its strength.

Signs this GS300 control arm may need replacing include clunking or knocking over bumps, steering wander, and uneven front tire wear; have the cause diagnosed first, since these symptoms can stem from other worn suspension parts. If a worn arm is the cause, replacing it restores the correct pivot point for the wheel.
