I know I read it all the time and its clear the differences in the cases but this thing has taken one hell of a beating and is still performing as good as ever.....I do have a ZR1 diff and tranny otw though

I probably said this before, but everyone with an 05 should be aware...
IMHO if you are drag racing your car more than once a year, it's just a matter of time before that case breaks and spits the pinion out the back.
When that happens, it virtually always either bends or breaks the transmission mainshaft, which is a $2000+ rebuild on the transmission, plus the cost of RnR the tranny.
The only good thing about the tranny rebuild is that it'll get rid of the first gear blockout issue at a dead stop 05's often have. But it's not worth the price to fix that.
If you plan to drag race an 05 you would be so much better off upgrading your rear to either a c5 or a 06+ and saving the cost of the tranny rebuild.

Can you guys clear something up for me? Are you saying an outright purchase is 2.5k then? Plus the tail housing for us 05 owners?
So can I "trade" my serviceable 05 diff as a core for an 06 up diff? Plus tail housing of course!
Looking for some ball park costs.

That's Zip's pricing. We have low mileage used 06 up diffs (3.42's only) for $1,600 outright plus $400 for a new 06 up tailshaft housing. We can upgrade the diff with C6 Z06 parts at no labor charge if the parts are purchased though us.

Can you pm me the full price on all of that? New diff with ZO6 parts and the housing. How hard of a swap is that?
