GM Genuine Parts are designed, engineered and tested to rigorous standards, and are backed by General Motors
GM Engineers design and validate OE parts specifically for your Chevrolet, Buick, GMC, or Cadillac vehicle
GM regularly updates production and service part designs to integrate new materials and technologies
What are Regular Production Option (RPO) Codes?
Three character codes that designate various features/options on your vehicle
Listed on the Service Parts Identification sticker (typically located in the glove box compartment or near the spare tire), or found by scanning a QR code on 2018 and up GM vehicles (located at the bottom of the driver side door pillar)
If the part listing designates an RPO code, look on your Service Parts sticker or scan your QR code prior to ordering to verify the part is correct for your application.
