Hello rg909,

I don't know the exact numbers but. I know you can order a stock 2wd with the 7700 Group option with 4.10 gears for increased towing capacity, and that's with 245/75-16 tires which are smaller than your 275/70-17's. So I think upgrade to the 4.10's would not be to drastic of a change, and would help your towing out nicely.
