After I broke the suregrip running mid 11s, I put in a spool and 35 spline Moser axles. Broke the ring and pinion when I got into the mid 10s.
A good axle is a good axle...doesn't make much difference what rear it's in.

The two that I have seen break. Pushed the caps back. One was a stick car the other was a b_body auto.
Once you have good axles and a spool in most 8 3/4 the left side(drivers side) bearing cap becomes the weak link   Now is the time to address that before it breaks and wrecks the ring and pinion I have two in stock, call me Dom 
But if you do it have it done right. The new caps have to be properly fitted, and the lash screwed back to where it needs to be.
Ive seen where people have had rears stay together as was, but blow up after changes to strengthen it because of improper fitment of the new caps. Mostly, the caps ending up to loose allowing lash to get sloppy and push out the retainers and boom.

You didn't ask and probably don't want to hear it, but..... Why keep pushing your luck with that poor 8-3/4? You know you are going to kill the thing. Sooner rather than later and probably with catastrophic results. Sell it now while it is still in one piece and worth something. A basic, cut down Dana with a spool isn't that expensive if you reuse your brakes. Sutton Engineering is a good source reasonably close to you. - Complete Dana 60 with a Moser spool and 35-spline axles = $1400.00

No, it didn`t blow YET but was curious about which let`s go first...........gears or axles. I`m assuming gears cos my 30 spline Dutchman`s look damn near perfect after many years of street/strip bashing and rerely hear about 8 3/4 axles lettin go it`s usually the cap/gears. Hopefully I have two more races lined up this Sunday but don`t want to be TOO confident just yet just because the axles look great................
