Changing from 3.73 to 4.10 gears
Hello all, After towing our new Reflection 320MKS from Eastern Iowa to Estes Park Colorado and back, I need more power for the hills. I have a 2015 F-250 with the 6.2 Liter engine. I have 3.73 years...

Yes, gears are a good way to increase power, but also affect fuel mileage.
You are running 4.56's to get performance towing HALF the weight of the OP.
Sure. I lost 1mpg unloaded, and gained almost the same towing. Totally worth it for the performance gain even if I didn't gain any MPG towing.
4.30's are a factory option from Ford, in that truck, with the same 6 speed and same 6.2L V8. To increase tow capacity.
Steeper gears are a common option from the factory to increase tow capacity.
Seems pretty clear to me.
