DFC GEOSPEC and 5000 Advanced Line

DFC GEOSPEC rotors are coated to resist rust better than conventional paint or zinc finishes, and they are machined to tight tolerances with balance inspection on vented rotors. The 5000 Advanced brake pad line is formulated for stable friction performance and uses premium shims to improve pedal feel and reduce brake noise. Together, these components are aimed at consistent rear braking performance on Ram 2500 and Ram 3500 applications.

Installation Notes

Before installation, confirm rear axle configuration and model-year fitment for your Ram 2500 or Ram 3500. The rotors are shipped dry and ready to install, which helps reduce prep time during a rear brake service. Follow standard brake service procedures, clean mating surfaces, and bed in the new pads according to the friction material manufacturer’s recommendations.

Each DFC GEOSPEC rotor is machined, inspected for critical dimensions, and checked for OE-spec compliance. Vented rotors are balance-inspected and corrected when needed. The rotors include a 12-month warranty against defects in material and workmanship. Part number 4502-40160 is built as a complete rear brake service solution for select Ram trucks.
