About this product

ACDelco Silver (Advantage) Coated Disc Brake Rotors are a quality, high value alternative for General Motors vehicles as well as most makes and models and are backed by General Motors. These rotors provide reliable vehicle braking power. Their robotic-applied, baked-on coating helps prevent brake pulsation, helps prevent the rotor from seizing to the hub, and provides superior rust prevention against harsh environmental elements such as rain, snow, and corrosive road sprays. They feature a non-directional ground finish that helps to extend brake pad life and minimizes thickness variation. They are also ready to be installed right out of the box, with no machining required. ACDelco Silver (Advantage) parts are a good choice for many vehicles on the road today. Some ACDelco Silver parts may have formerly appeared as ACDelco Advantage.
