hb pro diff?

[RC-Monster Mike]

The diff sets sold here include the bearings and drive cups, stampy. Put them inside a hybrid bulkhead and you come out pretty close in price to the 8 spider set with the cases(which aren't often in stock), but you have bulkheads in addition to the diffs. The diffs themselves are less expensive than the UE 8 spider diff sets. And yes, all the gears are hardened.
