Stock Rear 8.5 to 9.5

Randy also put an AXN in his Denali. He can tell you about the driveshaft mod for the 900. @randeez

Matt's 8.6 is holding up because he has AWD still if memory serves.

I’m not against upgrading by any means as I probably will at some point in the future but for reference, I’m making 1,000hp and have had zero issues with my 10 bolt running a TruTrac with original ring and pinion. I beat the crap out of my ride too. Just sayin, might not be needed for a light build if you replace the G80.

Good to know !! I've got my TrueTrac sitting here and the new cast alum cover
with the studs/etc to strengthen everything up.. I had shoulder surgery so
it'll be a while before I can get it in.. Hopefully the stock G80 holds up for a
couple more months !!!
Now if I can get a darn tuner to get me dialed in! I'm thinking of buying the
HP Tuners myself and try to clean up the tune

To give the rear more chance to live, should we always be in 4WD auto for spirited runs? Or will that make zero difference?

I guess hard launches should always be in 4WD hi? I'm mainly talking about hard street runs with a hard 1-2 shift that screeches the tires.
