The BD Diesel Rear Differential Cover with Rear Coil Spring (RCS) clearance is an enhanced design specifically engineered for AAM 14-Bolt axles in applications with rear coil springs. This heavy-duty cover promotes cooler, longer gear life by actively deflecting oil back onto the ring gear and into the pinion gear for optimal lubrication and reduced heat and wear. The cover features an extra capacity sump located at the bottom for the gears to pick up oil, along with internal and external cooling fins to maintain low operating temperatures. The cover comes gasketless, utilizing an integral re-usable Viton O-Ring seal, and includes a magnetic drain plug, stainless steel allen head cap bolts, and a fill plug.
