NBDRK321JMK is an NTN BCA differential bearing kit, put together for differential rebuild work. A differential lets both driven wheels turn at different speeds, which is what allows a vehicle to corner without scrubbing or hopping its tires, and its bearings keep that gearing supported. It is a genuine NTN BCA part from Pro Gear and Transmission. Call us with your axle details to confirm the kit and proper fit for your rebuild.
