Some ACDelco GM Original Equipment parts may have formerly appeared as GM Genuine Parts (OE) or ACDelco Professional
GM engineers design and validate OE parts specifically for your Chevrolet, Buick, GMC, or Cadillac vehicle
Original equipment parts are designed to work with your GM vehicle safety systems — aftermarket replacement parts may not meet the same OE safety regulations, depending on the part type
GM regularly updates production and service part designs to integrate new materials and technologies
