BD Diesel bdd1061825

BD Diesel differential cover for 2003–2015 Dodge 2500/3500 and 2001–2013 Chevy Duramax 2500/3500 designed to improve gear lubrication and cooling. Its internal geometry deflects oil back onto the ring gear and into the pinion to reduce heat and wear while an extra-capacity sump helps gears pick up oil. Includes cover, reusable Viton O-ring, stainless allen bolts, fill and drain plugs, and a magnetic drain plug for serviceable protection.
