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
As for the OP.......the ONLY thing that is going to survive in a decent HP radial car is a Dana or a 9". RADIALS BREAK CRAP. We have a chromoly housing in our radial car and bent it several times. The new housing is also chromoly, but has .250 wall axles tubes and is braced like you would for a Pro-Mod car.......2800lbs, dead hooking tire and going 1.0 60fts STRESSES parts

I'm confused, how is the rear of the pinion supported differently than a Dana? Just trying to understand.
