GM 10 Bolt 8.5- PINION BEARING SET-UP KIT

These bearings are perfect for the master installer or the first timer. They are honed to slide on and off the bearing surface by hand allowing you to easily change the pinion shim to achieve that ideal pattern. Once you get your correct pattern press on your new bearings and you’re done. If you do not have a clamshell style puller these bearings are essential.
