BD Diesel USA is a performance-oriented company specializing in high-quality diesel and heavy-duty truck components and upgrades. Their products are engineered to handle high pressure, high temperature, high load, and extended operation, not just occasional use. With years in the field (including intensive hours of idling, towing, and heavy usage), the BD Diesel's engineering and R&D is informed by real use cases.
BD's design deflects the oil back onto the ring gear and into the pinion gear for cooler longer life. Other differential covers are large and bulky resulting in lubricating oil being flung off the ring gear causing addition heat and/or wear.
