Differential cover Breakage

Alright this is pretty hard to search, so I figure I'll just ask.
Has anyone on here ever broken an aftermarket diff cover?

There's alot of talk about strength and this is thicker/stronger than that, but I've never heard of anyone breaking any of them, particular concern for SOLID because of the price

I have seen pics of solid covers that have cracked. they are cast so they are slightly more prone to cracking...... but...

I've also seen broken housings, cracked tubes, bent links, etc....

its all about how hard you hit 'em :rofl:

I did fund this sweet link though...not sure if it helps

Here's another good clip.
I know other competitors aren't tested but this guy
bashes the heck out of the ARB cover.

A buddy of mine has the Solid covers on his 30/8.8. He's broken a couple of the ribs off the covers, but not enough to fully crack it or make it leak.
