Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are built for drivers servicing front brakes on 1979-1991 Chevrolet and GMC trucks and SUVs. The rotor coating is applied to protect against corrosion while remaining safe for the friction surface during break-in.

This kit is a practical choice for Chevrolet K20 and K20 Suburban, GMC K2500 and K2500 Suburban, Chevrolet V20 and V20 Suburban, plus Chevrolet V2500 Suburban and GMC V2500 Suburban front brake applications.
