call Van Haisley, there is some sort of tab or something you weld/bolt onto the housing that keeps alil pressure on the ring so it won't flex under high load. I don't know exactly how it works/connects to the housing but heard him talking about it at scheids.

 

I am thinking the same but the ARB has me messed up cause I have to have thick gears for it. It was setup right, I spent hours making sure it was shimmed right, wear pattern was perfect and backlash was dead on. Looks like the pinion went first then took out the ring as you can see the ring is broken with a pattern. Not sure what to do if the next set doesnt hold up.
