Product Details

The DFC Brake Rotors - GEOSPEC Coated line focuses on corrosion protection where the rotor hat and non-friction surfaces are exposed to moisture and road debris. For rear brake service on Chevrolet Express 2500, GMC Savana 3500, and related GM platforms, this rotor set provides the correct application coverage listed in the fitment data. If you are replacing worn rear rotors on a Chevrolet Silverado 1500 HD, GMC Sierra 1500 HD, or Chevrolet Suburban 2500, part number 4002-48020 gives you a cataloged match for the specified rear position.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Reasons for Replacement

• Brake pulsation or vibration from rotor wear
