Tighten up steering response and quiet a worn front end with the Mevotech Supreme control arm, part number CMS101205. This front left lower (rearward) control arm and ball joint assembly drops in as a direct-fit replacement for the 2007-2013 Mercedes-Benz S550, the 2007-2009 S600, and the 2011-2013 S63 AMG — see the Buyer's Guide tab for engine-level fitment.
As a Mevotech Supreme lower control arm, it locates the wheel and, through its integrated ball joint, allows steering and suspension travel. If a failed arm or ball joint is behind clunking over bumps, uneven front tire wear, or loose steering, this S550 control arm replaces those worn pivot points. Sold individually for the front left lower rearward position; order the matching part for the opposite corner if needed.
