This is the factory hardware necessary for installation of a OEM Z51 Spoiler. Until now, these adhesive pads have only been available in brand new spoiler kits from GM, and were not sold separately. Wildhammer Motorsports has created a template based on these adhesive pads, and made them available to be used with this kit, to allow for easier installation!
General Motors is an OEM manufacturer. GM designs and creates the vehicles and the parts for them for makes such as Buick, Cadillac, GMC, and Chevrolet. All GM branded parts are OEM standard quality components and were designed and manufactured to either be on the vehicle from the factory or purchased after the fact as an accessory.
