what is a good posi??
Some factory truck come already with the eaton g80. I would think the z71's do as well.
If you are in the market for a posi, Eaton is probably going to be a pretty good choice.
Then, there's the T2 diff's, that are made for the 8.5" 10 bolts..... wonder how they wold work.... Hummers use Torsen diff's too, so they must work decent..
