GM Genuine Parts Strut Mount Bearings are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These bearings are located at the top of the suspension struts. They are designed to allow the struts to pivot with reduced friction during steering maneuvers. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
