Weight and torque is what kills an 8.75... It just doesn't matter what you do to them, you can't fix the inherit flaw in the design. The gear end of the pinion is NOT SUPPORTED. The pinion flexes, comes away from the ring gear....saws teeth off and that clogs up the works and SOMETHING has to give and that is usually the case. Housing flex is NOT what kills them, it is pinion flex. Better cases, billet caps and all that other stuff is like a bandaid on a gunshot would. Not much help



I think that's the best explanation I've heard (ever) describing the built-in design flaw of an 8.75" Chrysler differential.
