ACDelco 18A813C Silver Coated Front Disc Brake Rotor

The ACDelco 18A813C is a Silver-line coated front disc brake rotor engineered as a high-quality replacement for a wide range of GM and non-GM passenger vehicles. Featuring a robotic-applied, rust-preventative coating, this rotor resists corrosion right out of the box and is ready to install without additional preparation or machining.
