The 217980 Eaton gear kit with pin and nut is a differential service component sold by Pro Gear and Transmission. It supplies the gear along with the retaining pin and nut needed to complete the assembly, so the mating hardware goes in together rather than being chased down as separate line items. Eaton part numbering keeps identification straightforward at the parts counter: reference 217980 when ordering or cross-checking against your axle build. Differential internals vary by model and ratio, so give us a call with your axle tag information and we will help confirm this is the correct kit for your unit.
