BD Diesel Differential Cover – Part # 1061825

The BD Diesel 1061825 differential cover is engineered to improve lubrication and extend the lifespan of your rear differential. Its innovative design deflects oil back onto the ring gear and into the pinion gear, promoting cooler operation and reducing heat buildup during heavy-duty towing or high-performance applications. Unlike bulky aftermarket covers, this model features an extra capacity sump located at the bottom, ensuring gears pick up sufficient oil for optimal performance. The gasketless cover incorporates a reusable Viton O-Ring, providing a reliable seal while simplifying installation and maintenance.
The cover is constructed from durable materials with internal and external cooling fins that help dissipate heat more effectively. Stainless steel Allen head cap bolts and a fill plug ensure corrosion resistance and ease of service. Compatible with Dodge models 2003 and up fitted with AA14-11.5 differential and Chevrolet models from 2001 and up with the same differential, this cover offers a robust upgrade for fleet and heavy-duty trucks. With a 36-month or 150,000-mile limited warranty, the BD Diesel differential cover is a reliable choice for maintaining drivetrain integrity under severe operating conditions.
Designed for ease of installation, this cover enhances oil management systems, minimizes wear, and prolongs differential life. Its magnetic drain plug aids in debris removal, maintaining oil cleanliness over time. Whether used in commercial fleets or personal heavy-duty trucks, this differential cover provides improved cooling, oil retention, and durability, ensuring your vehicle’s drivetrain remains protected and performing at its best.
