I am wondering what gears I should put in my truck for the best MPG. I currently have a 2000 Ranger 4.0L, 4X4 with the 4.10's. I have heard that I could get better mileage with 3.27 or even go to 3.55 to keep some power. Would I also need to change out the front gears for the 4X4? I don't offroad and use the 4X4 when it gets slick on the roads or snowy. Looking for the best MPG. Installing my E-Fan this weekend.
I have a 1967 Mustang and have a T5 running 3.55, it gets 20 on the highway with a very modified V8. I would love to get that with my truck. By the way, I am selling my Mustang, unfortunately.
