However, none of us can get the newer units to last before they fail. I'm seriously wondering if Auburn's quality has gone downhill within the last few years. Could be a situation like some have experienced with the Torsen T2R, the high bias unit. They used to be considered the best for handling applications, and I know somewhere along the line they switched to a lesser quality material, and people started breaking cases as they became very fragile.

I still think the cone clutches in a 7.5 ten bolt unit are too small to handle the power an average LS engine makes. But that's more the fault of GM putting such and undersized rear in these cars.
