Restore precise wheel location and confident handling with the Mevotech Supreme control arm and ball joint assembly, part number CMS101300. This rear lower rearward unit installs as a direct-fit replacement for the listed applications: the 1999-2013 Porsche 911, the 1997-2012 Porsche Boxster and the 2006-2012 Porsche Cayman — see the Buyer's Guide tab for engine-level coverage. The control arm locates the suspension and lets it travel through its arc, while the integrated ball joint links the arm to the steering knuckle so the wheel can pivot and articulate.
Worn control arm bushings or a failing ball joint can produce clunking, wandering, loose steering or uneven tire wear. If those symptoms trace to this component, this Mevotech Supreme suspension control arm replaces it. Sold individually; order the matching arm for the opposite side if it is also worn.

Will this Porsche 911 control arm fit my car?
It is a direct-fit replacement for the 1999-2013 Porsche 911, 1997-2012 Porsche Boxster and 2006-2012 Porsche Cayman. Check the Buyer's Guide tab to confirm engine-level coverage for your vehicle.
What position on the vehicle is CMS101300?
It is the rear lower rearward control arm with an integrated ball joint. Order the matching arm for the opposite side if that side is also worn.
What is this Mevotech Supreme lower control arm made of?
It features cast aluminum construction, built to OE-level tolerances, and the ball joint carries an added surface treatment to help resist rust build-up.
Does the ball joint come attached to the arm?
Yes. The ball joint is integrated into the arm, so it arrives pre-assembled and installs as a single unit — you replace both together.
What are the signs this Boxster control arm may need replacing?
Clunking over the suspension, wandering steering, a loose feel or uneven tire wear can point to worn bushings or a failing ball joint. Diagnose the cause before replacing.
