The BD Diesel Differential Cover Pack is designed for heavy-duty applications on Dodge Ram 2500 and 3500 models from 2006 to 2013. This set includes both front and rear covers, engineered specifically to enhance oil retention, cooling, and overall differential longevity. The rear cover features an extra capacity sump located at the bottom, allowing the gears to pick up and circulate oil more effectively, which contributes to cooler operation and extended component life. The covers are gasketless, utilizing integral reusable Viton O-Rings to ensure a secure, leak-free seal and ease of maintenance.
Designed with internal and external cooling fins cast into the aluminum, these covers help dissipate heat from the differential, maintaining optimal operating temperatures during heavy-duty towing or high-performance driving. The deflection design of the covers directs oil back onto the ring gear and into the pinion gear, promoting more consistent lubrication and reducing the risk of oil fling-off common with other bulky covers. Stainless steel Allen head cap bolts and fill/drain plugs are included, providing corrosion resistance and reliable service life. These features, combined with magnetic drain plugs for debris collection, make the BD Diesel differential covers a practical upgrade for fleet and performance vehicles.
Installation requires adherence to proper procedures, including cleaning mating surfaces and replacing gaskets if used during reassembly. The covers are built to fit specific Dodge Ram models, ensuring a precise fit and maximum protection. Backed by a 36-month or 150,000-mile limited warranty, these covers are a durable solution for extending differential life and maintaining optimal lubrication during demanding conditions.
