Get the glove-box RPO code for the rear axle, most reliable way to know. My 1500 Silverado has the 14 bolt rear because I got it with the NHT Max Tow package. But it's still a 1500.

The 1500 Denali comes with 2 different axles, if it is AWD its the 8.6" 10 bolt, if 2WD its the 9.5" 14 bolt.

I was thinking about it and the 10-bolt will be fine up to pretty big power behind an AWD... At a 400 dyno only 240 is going back to it. I doubt mine even has close to 400 at the wheels...

Check my sig.

all denalis are 1/2 tons but the hd sierra denali which iirc started in 10

the 1500hd is identical to the 2500ld...just a marketing/name change

the denali in question in this thread is definitely a 1500.

Didn't know the AWDs had a 10 bolt...sucks for them, but I'm sure with all the drivetrain loss they don't get punished. Thanks for clarifying that it's a 1500.

Its not only the drivetrain loss. Only 60% goes to the rear versus the full 100%. This means the AWD gets only 60% of the beating the 2WD trucks get in the rear. Thus the ability to cut corners.
