The PPE 238053020 Black Heavy-Duty Cast Aluminum Rear Differential Cover will help dissipate heat on the 11.5" or 11.8" rear axle in your 2019-2022 Ram 6.7L Cummins. To minimize friction and improve lubrication, this differential cover has specially engineered internal heat sinks and exterior cooling fins. This differential cover provides strength and heat dissipation as it is cast from heavy-duty A356.0-T6 aluminum. By maintaining viscosity for a longer period of time, increased fluid capacity offers greater thermal endurance. A fill plug with a strong Neodymium magnet removes harmful ferrous metal fragments from the gear lube.
