Keep your front suspension precisely located and free of play with the Mevotech Supreme control arm and ball joint assembly, MPN CMS861310. This front left upper unit installs as a direct-fit replacement for the 1992-2000 Lexus SC300 and SC400 and the 1993-1996 Toyota Supra.
The control arm locates the wheel and lets it travel through its arc, while the integrated ball joint allows the knuckle to pivot for steering and suspension movement. As a Mevotech Supreme suspension control arm, it carries application-specific upgrades built for high-usage passenger vehicles, SUVs, fleets and working trucks.
Whether you're replacing an SC300 control arm or an SC400 control arm, a worn suspension arm or ball joint can show up as clunking over the front end, loose or wandering steering, and uneven front tire wear — if a failed arm or ball joint is the cause, this assembly replaces it.
