GM Genuine Parts Disc Brake Rotors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. GM Genuine Parts OE Brake Rotors are the true OE parts installed during production or validated by General Motors for GM vehicles. GM engineers spent many years developing, testing, and validating brake rotor solutions for each brake corner for every GM vehicle. GM Genuine OE rotors are designed, engineered, tested to rigorous standards and backed by General Motors.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
• OE brake components are specifically designed to work with your GM vehicle safety systems
• Most GM OE brake rotors sold in the U.S. are Ferritic Nitro-Carburized, or FNC rotors
• FNC rotors are hardened and strengthened during an extended manufacutirng process that helps provides an extra defensive barrier against the corrosive threat of water, sale, and even acid rain
• OE brake systems and components are required to meet Federal Motor Vehicle Safety Standards (FMVSS)
• OE brake components are specifically designed to work with your GM vehicle safety systems
• Carbon ceramic brake rotors are used in high performance vehicles because the carbon fibers provide strength and the ceramic rotors are lighter than standard iron
• Designed to meet GM resonant frequency separation requirements to help reduce the risk of brake noise
• Designed to customer vehicle parameters to resist thermal roughness
• Manufactured to OE Dimensional Controls to help reduce the risk of pulsation
• GM engineers specify rotor material compositions for each GM vehicle application
• 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 Engineers design and validate OE parts specifically for your Chevrolet, Buick, GMC, or Cadillac vehicle
• GM regularly updates production and service part designs to integrate new materials and technologies
