Hmm...will it last?

The 8.25 is good , it's the use that kills any diff, or unless they are being used well beyond there power ability.

I have a D-35 which is pretty close to a 8.25 in many ways and i haven't broke it with well over 500hp, road and drag in a 4000lb vehicle...

But im not having wheel hop or any other issues that kill any diff
