OEM JZA80 Supra USDM "B" Series 220mm Differential Final Gear Kit.
As per any bearing after being many of years old they will need to be replaced. Great to do if your doing a re-fresh of the whole differential.
Note: This suits only the 220mm early JZA80 Series 1 differential found in 6sp models.
This does include a new front pinion nut, crush spacer and seal, along with crown bolts.
