Can anyone confirm if this is true or not? I saw it listed on an online vin decoder, as well a car and driver spec page? Thank you.

On our 07 classic 2500hd it is a full float iirc. If you are looking at them you could pop off the hub cap cover and confirm. I would think it would be a full floater as most of the work vehicles I see are 2500s.

Yeah, easiest way to tell is pop a rear center cap and look for the ring bolts.

Most of those should be full float, but from what I gather there are a few semi floats out there that use the smaller 9.5" ring gear vs the 10.5" in the full float.

This is some trucks we're looking to buy, but we won't actually be looking at them for a couple more weeks, I'll have to look closely at them!
