I don't believe that to be the case after about 2002 or whenever they got rid of the non HD 2500 and 1500hd. Got a pile of newer 2500 GM gasses at work and they sure look like AAM axles under them. Quick parts search revealed the same.

The 2500HD does not have a semi floater...... it has a full floater... ask me I have one. The standard 2000-2007 2500 and 1500HD had the semi floater with 9.5 Axel, yep had ones as well. So the difference on the 2007.5 and up is only the spring pack and rear diff goes from 10.5 to 11.5.

Spoon is quite wrong in his statement about axles.
The only trucks since 2000 that do not have full floating axles were the 2500(non hd) and the 1500hd. Both of those trucks are quite rare. All 2500HD and 3500 trucks since 2000 have the full floating axles and are quite similar.
Well, it would appear that I was wrong about the semi-floating vs full floating. My apologies, I thought that was still the case which explained the difference in the rear axle size between 3/4 and 1 ton. I will eat some humble pie and sit out the rest of this thread.
