I guess the differential could break... guess I've never heard they were weak though. Buts that's a manual. That's the game.
The diff could break in my car too just not as likely

I believe cdflyer in this very thread ran 12.0 with just a good tire. Stock otherwise. Broke an axle
the s550s are doing that too? Ford built them right then. I understand the SS diff is pretty sturdy, but pretty things do break. I haven't heard of one breaking. What I was told about the SS diff was the body is cast iron unlike the 5th gen v8 diif. I broke one of those.

I think but don't know that the ZL1 diff looks about the same as the SS although the Z and 1LE have the fancy electronics. If they are the same durability then maybe the SS is all good there. And of course Chevy suggests the 5th gen ZL1 diff if we need a 1,000+ RWHP boat anchor.
