Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS401107
Keep steering crisp and the front suspension geometry tight with the Mevotech Supreme control arm and ball joint assembly (CMS861242), a front upper unit that locates the wheel and pivots through its integrated ball joint. It installs as a direct-fit replacement for the 2006-2015 Lexus IS250, 2016-2021 Lexus IS300, 2011-2021 Lexus IS350, 2006 Lexus GS300 and 2007-2011 Lexus GS350.
As a front upper arm, it positions the wheel and controls alignment while the built-in ball joint lets the knuckle pivot for steering and suspension travel. Worn bushings or a loose ball joint on the original can cause clunking over bumps, vague steering or uneven tire wear; if the arm is the cause, this IS300 control arm replaces it. Sold individually; order two for a complete front replacement on both sides.

Is this a front upper or lower control arm?
This is a front upper control arm and ball joint assembly.
What are signs this control arm may need replacing?
Clunking or knocking over bumps, vague or wandering steering, and uneven front tire wear can be signs of a worn control arm bushing or ball joint. Diagnose the cause before replacing.
Does this assembly include the ball joint?
Yes. The ball joint is integrated into the arm, so replacing this assembly replaces both the control arm and its ball joint in one unit.
Is the IS300 upper control arm sold individually?
This listing is for one assembly. These arms install as left and right pairs, so order two if you want to replace both front sides together.
