PRODUCT DESCRIPTION
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
Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE)
GM Genuine Parts are designed, engineered and tested to rigorous standards, and are backed by General Motors

GM regularly updates production and service part designs to integrate new materials and technologies
