Steady your steering and keep the front suspension precisely located with the Delphi control arm TC6302, a direct-fit replacement for the 2001-2005 Lexus IS300. It installs in the front right lower rearward position, so if you're shopping for an IS300 front lower control arm to address loose handling, uneven tire wear, or clunking from a worn arm, this drops in as the correct replacement (see the Buyer's Guide tab for the full engine listing).
Delphi applies its OE steering expertise to this aftermarket arm, backed by extensive dimensional and material analysis for close OE-to-aftermarket compatibility.
The control arm pivots at the frame and carries the ball stud, locating the wheel and allowing suspension travel while helping maintain alignment geometry. Replace worn arms in pairs where practical for balanced handling.
