The NTN BCA NBRA313 is a differential rebuild kit that gathers the bearings and seal hardware for the ring and pinion area under one part number: head and tail bearings, carrier bearings, a pinion seal, a pinion nut, and a crush sleeve. It is built for a rebuild that reuses the existing gears, so shims, the cover gasket, and axle seals are not part of it and should be picked up separately. The crush sleeve is a fresh spacer for reassembly, which is why a kit includes one. A genuine NTN BCA part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
