Bring back tight, controlled steering and a solid front end with the Mevotech Supreme control arm and ball joint assembly (CMS801116), a direct-fit replacement for the 1990-1997 Mazda Miata. This FRONT UPPER unit pairs the control arm with its integrated ball joint in one piece, so it locates the knuckle, pivots through suspension travel, and lets the joint articulate for steering and ride motion — making it a clean upgrade over worn Miata a arms.
Mevotech Supreme parts are engineered in-house with application-specific upgrades for added durability, built for high-usage passenger, SUV, fleet and commercial vehicles.
Worn control arm bushings or a failing ball joint can bring clunks over bumps, loose or wandering steering, and uneven tire wear. If a bad upper arm or joint is the cause, this Miata upper control arm assembly replaces it. See the Buyer's Guide tab for engine-level fitment.
