Most know but so everyone will know.
My truck is mostly stock.
It's a 94 Ram 1500 5.2l, 2wd, auto, short bed and standard cab.
It has stock tire size and wheels, no plan on changeing it.

I want to tow some with the truck, mostly a bass boat and would like to get a little bottum end.
Would 4.10's be the best bet or maybe look at some 3.73's? I don't want to go overboard just a little something more.

 

3.92 or 410 are your choices. 410s would be better off the line, the 392s better on mileage but still do ok.
Expect to turn about 2350rpms at 70mph with 392s and about 2600 with the 410s same speed.
