Gear selection help!!

Ok i have 2006 F350 8" lift. I will be running 37" tires for the time being but might go up to 38" later. My question is, if i put in 4.56 gears and never end up going to a 38" tire will it be too low? Or will it be acceptable?

Thanks, DB

I think 4.10 or 4.30 would be a better choice unless you're doing some very heavy towing.

once I get the $$$ I am going to get 37" tires and 4.56 gears...I tow and don't have a long commute to work, if you don't tow or don't go with 38" tires 4.30 gears will probably be better for your mileage...

I tow about 9k 6 to 10 times a year. I just dont want to regret my decision. Mileage is fairly important, right now i get between 14-15 mpg.

4.56 gears will get you back to 3.73 with your 38s, but if you plan on staying with 37s, 4.30s are the gear of choice.
