Keep the front wheel firmly located and steering movement precise with the Mevotech Supreme control arm (CMK90378), a front left lower control arm and ball joint assembly that installs as a direct-fit replacement for the 2001-2002 Kia Rio. This suspension control arm links the chassis to the steering knuckle through its bushings and integrated ball joint, positioning the wheel while allowing the pivoting motion needed for steering and suspension travel.
Mevotech Supreme parts are engineered in-house with application-specific upgrades and built for high-usage passenger vehicles, fleets and working trucks, with Labor Saver designs that speed installation.
If a worn control arm bushing or ball joint is the cause of clunking over bumps, loose or wandering steering, or uneven tire wear, this lower control arm replaces the failed original. It serves the front left lower position; inspect the opposite side and replace as needed for balanced handling.
