LKQ shows you the donor vehicle and VIN and photo of plate on door. They have plenty improperly listed so you have to dig.
The VIN on that 2008 is from a 2012 AWD as you mentioned and of course it will have an 8.6 axle.
The 6.2 GMC 1500 Pickups in our generation are also equipped with the 9.5" semi-floater but of course are set up for leaf springs. They come with 3.42 or 3.73 gears. The 2007-2009 6.0 Vortec Max 1500s also ran this same axle and some of those might have 4.10 gears (2007-2008). All of them will show RPO AXN on their build sheet. VIN number for the engines are either 2 or Y
Thanks for the info on the leaf spring options! At the end of this thread, assuming I make it there, I'd like to put together a master list of all direct bolt up axle options for '07-'14 GM full-size SUV/SUT. I think it would shorten the learning curve for anyone who wants to do this. A little surprised I haven't come across one yet?
I haven't been able to find an RPO list with AXN on it? Is it an actual RPO code or an Option code or Axle ID Stamp maybe? Just curious what it says/distinguishes? I thought it signified a 14 bolt 9.5 rear-end out of 2wd? but I also first saw the inside of a diff 3wks ago lol
This all the AX_ that are on the best list I have? It "says" Master List at the top but who knows? 188 pages

Earlier today I closed some(like 12) tabs and started a fresh search for any and all things related to this, and there were only 2 links in the first 4 pages that I hadn't already visited, maybe 10 links through first 8 pages...
Today was 23rd straight day I've been at this. At first it was like cramming for a test, and I was a little hesitant to ask questions until I had a better grasp of what I was asking about. Felt a lot like this
I really appreciate all the guidance and sharing of knowledge. Call it karma, call it the golden rule, call it whatever you want; it's fact of life....when it goes around....it comes back around.
