BD Diesel Differential Cover

The BD Diesel Differential Cover line gives heavy-duty trucks a performance replacement for the stock rear or front axle differential cover. The cast covers are built to keep gear oil working where it matters. Many standard covers let lubricant get flung off the ring gear. BD's design deflects oil back onto the ring gear and into the pinion gear, which helps the drivetrain run cooler and last longer.

Key Features:

• Engineered cover shape that keeps oil on the gears
• Extra-capacity sump at the bottom of the cover, so the gears can pick up oil and the cover holds more fluid
• Internal and external cooling fins to help shed heat
• Magnetic drain plug to catch metal particles in the fluid
• Stainless steel hardware
• Re-usable Viton O-ring seal in a gasketless design, for leak-resistant sealing and easier servicing

BD Diesel is known for diesel truck performance parts. These covers add drivetrain protection and cooling for trucks that tow, haul or work hard. Select the variant that matches your axle and application.
