Lubricate and Cool Your Gears!
BD Diesel Differential Covers are specially engineered to keep oil on the differential gears during operation. Other differential covers are large and bulky resulting in lubricating oil being flung off the ring gear. BD Diesel's design deflects the oil back onto the ring gear and into the pinion gear for longer gear life. The BD Diesel Differential Covers feature an extra capacity sump located at the bottom to help keep oil available for the differential gears. These diesel differential covers feature internal and external cooling fins to maximize heat transfer away from the gears and oil. The cover bolts are constructed from stainless steel, and the drain plug is magnetic to help keep metal from tearing up your gears. These covers feature gasket-less installation, utilizing an integral, reusable Viton O-Ring.
