Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS101183
Help keep your rear suspension tracking true with the Mevotech Supreme control arm, part number CMS501045. This rear left lower unit installs as a direct-fit replacement for the 2004-2009 Cadillac XLR and 2005-2013 Chevrolet Corvette (see the Buyer's Guide tab to confirm your engine and configuration). As a Mevotech Supreme lower control arm, it positions the rear wheel and, through its integrated ball joint, allows suspension travel while helping keep alignment angles stable.
This Mevotech Supreme suspension control arm and ball joint assembly is sold individually; replacing the left and right sides together is recommended. If a worn control arm or a failing ball joint is behind clunking over bumps, uneven rear tire wear, or loose handling, this replaces them; diagnose the cause before ordering.
