This is a stock replacement aluminum control arm for your Cobalt, HHR, Pursuit, Ion or G5.
Important: there are two different sides and two different sizes of ball joints. Left is drivers side, Right is passengers side. There is a 19.5mm ball joint, and a 20.5mm ball joint. Generally, LSJs come with the smaller ball joint, and LNFs come with the larger. The LNF arm can be installed in place of an LSJ arm, but you must spread the spindle to fit the larger ball joint. You cannot install the smaller ball joint control arm in the larger ball joint spindle. We recommend installing the correct arm for the specific vehicle.
Shorter end links may be needed depending on your strut/sway bar combo.
