Locate the front wheel and hold steering geometry in place with the Mevotech Supreme control arm CMS20347, the front right upper suspension control arm and ball joint assembly with the ball joint and bushings already installed. It fits as a direct-fit replacement for the listed applications, including the 1988-2000 Chevrolet C2500, 1989-2000 Chevrolet C3500, 1995-1999 Chevrolet C1500 Suburban, 1992-1999 Chevrolet C2500 Suburban, 1996-2002 Chevrolet Express 2500 and Express 3500, plus the matching GMC C2500, C3500, C1500/C2500 Suburban, Savana 2500 and Savana 3500 and the 2000 C3500HD — see the Buyer's Guide tab for the full list.
It ships with the part-specific castle nut and cotter pin to secure the ball joint, and a protective surface treatment helps resist corrosion. If a worn upper ball joint or failed control arm bushing is behind clunking over the front, loose or wandering steering, or uneven front tire wear, this assembly replaces the arm, ball joint and bushings in one piece.
