GM Genuine Parts Disc Brake Rotors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. Disc brake rotors are mounted to the wheel hub where the calipers press your vehicle's brake pads against the disc surface to help slow down the vehicle. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

• Most GM OE brake rotors sold in the U.S are Ferritic Nitro-Carburized, or FNC rotor
• These rotors typically last two times longer, compared to non-FNC rotors, due to improved pad wear behavior
• OE brake components are specifically designed to work with your GM vehicle safety systems
