Product Details

DFC designed this brake kit to simplify rear brake service by pairing application-matched friction and rotor components. The GEOSPEC rotors use a protective coating that helps resist rust better than conventional paint or zinc finishes, while the 5000 Advanced pads are prepared to reduce initial break-in time and deliver consistent stopping response from the first stop. This makes the kit a practical choice for Ram 3500 rear brake replacement and Ram 4000 rear brake service where OE-style fit and stable performance matter.

Part number 4502-40164 is engineered for rear axle applications on 2019-2022 Ram 3500 and 2019-2021 Ram 4000 models listed below. If you are searching for a rear brake kit for a 2022 Ram 3500 11.5-inch rear axle or a 2019-2020 Ram 4000 rear brake replacement, this kit is built for those exact service needs.
