Time to upgrade the diff and axles... any advice?

Spool is out of the question due to street use. I have a set of MT ET street radials, but may swap to the ET drag in the future.

Any opinions on a Good strong diff that locks up extremely quick and will last? Car will be launched on a 410w on nitrous. Thanks.
 
new diff upgrade.

strange axles will likely go in. I need to do it before I break. Track is so far away (130 mile round trip) that the tow bill would nearly cost what a new diff would cost.

The diff is what i cant decide on... auburn pro, strange, eaton... etc.

Thanks.
 
Iwould run an eaton unit and 31 spline superior axles reason being the axles are warrented for 3 years and the eaton is awsome because u can take corners ant it unlocks so its not skipping like a full spool i have the same set up in my car and i love it. and i also drive over 100 miles to the track
 
I had trouble with Moser in my 85. The bearings did not fit right, the welds looked rough. To their credit, they did send me parts to fix the problems. For what its worth.
 
I bought the Alloy USA Axles off Summit. Same type of metal for less $$.

Go with 31 spline axles, get a decent diff, and a girdle and forget about it.

Id love to get the Eaton electric diff. But $800 is a little much I think.
