Mevotech has a new addition to its Supreme Chassis control arm line, the new MS50122/MS50123 Control Arm Assembly for the 2005-2009 Chevy Malibu, Pontiac G6 and Saturn Aura chassis. Because of its unitized type ball joint, which cannot be replaced separately, Mevotech has designed a complete replacement part with all bushing and pinch bolts included, according to the company.
