F250 3.73 to 4.30 axle ratio
I have a 2017 F250 4x4 crew cab, 160" wheel base, 6.2l gas, 3.73 gear ratio. I am trying to see if having 4.30 axle ratio gears installed will make much difference regarding 5th wheel towing. I noti...

Last three responses are spot on in their own respects. There are many ways to increase torque multiplication and maximize running in the powerband.
One not mentioned is running the smallest diameter, width and smoothest tread tires possible.
One advantage to gearing down is yes, the furthest downstream you can maintain the low gearing, the more efficient it is. But compared to years past when 2-4 sped transmissions allowed little variable between pulling power and efficiency or high speed travel, now you can have both to a good extent. Enough that re gearing something with a 6-10 speed transmission is of deminishing ROI.
Yes it will help, but will it help $3000 worth? You could buy the same truck with deeper gears for less total expenditure. You could spend twice as much and get triple the re gear increase with forced induction, same gears. Or spend a shade more than that and get diesel.
Not enough juice for the squeeze with re gearing when so many other options are present. Unless you're not worried about $ spent per hp or ft lb gained.
