The NTN BCA NBDRK321Q is a differential bearing kit, sold as a complete kit. The differential allows the two sides of a drive axle to spin at different speeds through a corner, and its bearings support the carrier and pinion so the gear mesh stays accurately positioned while everything turns. Buying the bearings as a kit keeps that work to a single part number. A genuine NTN BCA part from Pro Gear and Transmission. Differential kits are application specific, so call us to confirm proper fit for your axle before you order.
