Max tow weight on gear ratio

Looking for the difference between the 3.42 and 3.73 max towing capacity?

What year and what transmission; also is it a diesel or gas engine and is the truck a 3500 or 3500 SRW or DRW?

For example a 2008, 2500 Mega Cab with an auto only offers a 3:73 and 4:10 the 3:42 is only offered in a manual transmission. This is per the Ram Body Builders Guide which I have included for your reference.

Per the Ram Body Builder's website Ram only offered the 3:73 gear set with the manual transmission for that year. The max towing weight would be around 13,100 LBS+/- 300 LBS depending on trim level and if it is a LB/SB truck.
