GAWR

It will be listed on your door jamb sticker.

The tire weight rating is there not GAWR

Your AAM rear axle is rated just under 11k lbs before GM derates it in their build with their choice of wheels and suspension.

So any idea of the front and rear axle rating or how I find it

In addition to the tire sticker there should be a sticker that looks like this.



They have always been on the driver door jamb on trucks I have owned.

T%here are TWO stickers on your door jam, one has the tire inflation information, the other the VIN sticker has GVWR and both Front and rear GAWR.

Some times a truck that has been rebuilt may not have the FAWR/RAWR certification sticker.
If its missing go to a GM dealer and have them run the VIN number for the trucks certification numbers.

The brochure that you sent me just has front axle rating not rear. I don’t have a sticker on door jam for axle ratings and truck was brand new when I bought it

I think this is the relevant portion from the link. I would definitely go to the dealer though and get a sticker. I believe that it was legally supposed to be there when you purchased the truck new and it could be an issue selling the truck down the road. This is typically where any service dept would scan your truck in for service and documentation. Odd that it is missing for this long and nobody has called it out. Maybe it is somewhere else that's not obvious.

The info in this photo grab should be correct but I would still double check with the dealer.
