Product Line Details

DFC GEOSPEC rotors are coated to resist rust better than conventional paint or zinc finishes, and they arrive ready to install without oil removal or extra prep. The 5000 Advanced brake pad line is formulated for stable friction performance, with post-curing and scorching used to reduce initial break-in time and support consistent stopping from the first stop. Together, the rotor and pad pairing is aimed at dependable rear brake service on Ram heavy-duty trucks.
