Ford F-250 7.3 Gas Engine Axle Ratios
Is there much difference in towing milage, and around town/highway mileage with the new F-250 7.3 gas engine with rear gear options? Considering 3.55 or 4.30 axles ratios. Any input is helpful.

Get the 4.30's. Keeps the engine in it's sweet spot when towing / hauling. I chose the deeper gears with my gasser and am very happy with it. I get at or better mileage that my friends with the 3.73 axle as the engine doesn't have to work as hard to get things moving. Transmission holds gears and doesn't hunt or shift excessively at all. I am running the 6spd.
