Im wanting to get more power out of my 94 auto supercab but I dont wanna kill mpg it has 3.08 gears I was thinking swap to 3.55 to keep mpg would there be noticeable power difference?

 

What motor do you have? 3.55 is the highest I would use. My 3.0L's are the same combo as you but have the 3.73 gear. Can get average of 20+ on the interstate and have nice power. Why Ford ever put the 3.08 gears in a Ranger.

I have 4.0 and 4speed auto

 

Im lookin to get better accleration and towing power would 3.55 help I swithed from the 225/14 to 235/75/15 thats when I noticed power loss

 

Problably be a lot better going to at least a 3.73 gear with them tires, especially for towing.

How bad will mpg suffer with 3.73

 

You want to keep the RPM below 2400 with the 4.0 to keep any real gas mileage.
