Firm up the front suspension and steering with the Mevotech Supreme control arm (CMS501098), a direct-fit replacement for the front left lower rearward position on the 2008-2009 Pontiac G8 and 2011-2013 Chevrolet Caprice. This control arm and ball joint assembly locates the wheel, carries the integrated lower ball joint, and lets the suspension travel and steer while holding the alignment angles in position.
Built by Mevotech for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks, this Mevotech Supreme suspension control arm swaps in for a worn factory unit. If the original arm's ball joint or bushings are the cause of clunking over bumps, wandering steering, or uneven tire wear, this assembly replaces them.
