Hey guys I was wondering what gear ratio you would reccomend for my truck. Im running the stock gears on my 07 F150 4x4 5.4. Im looking for a little more pickup, a little better gas mileage if thats possible, and to make life easier on my transmission. Im running 35"s right now and plan on bumping up to 37"s in a year or two. I know I can get by with what I have for now but since I'll have to do it anyway to run the 37"s Id like to go ahead and do it.

 

4.56 for highway mileage or 4.88 if you tow or are in the city mostly.

 

or 4.88 for the most power.

 

with 37's i personally would want the 4.88's

 

4.88's
