Axle ratio with "Trailer Tow Group"

[440pursuit]

I'm looking at buying a used 2021 Ram 1500 for towing 9000#. I found the window sticker that shows standard equipment as a 3.21. In the options section it shows Trailer Tow Group" but no upgraded axle ratio. Online searches just says "upgraded ratio". I want to know the actual ratio. Other trucks I've looked at show 3.92 in the option section, but not the "TTG option" Does the Trailer Tow Group include the 3.92? Thanks

The axle ratio is separate from the trailer tow group, Afaik.

Not sure if its in the group or not but it should be listed on the window sticker. Its safe to say if it doesn’t say it then it doesn’t have it

As noted by others above, the rear axle ratio is a separate optional item, so your only course of action is to change out the current gearing.
For the rear end it isn't all that expensive-a new ring/pinion set, some bearings, gaskets, crush sleeve. But the front, that's a whole different issue. ZF will not sell just components, you have to purchase the complete assembly, and that is prohibitively expensive.
Your best bet would be to try to find a complete front end out of a written off truck.
