Default regearing question

Hey guys,
Looking for some help here. I Have a 2000 F150 lariat with a 6 inch fabtech lift and I want to get 37 inch tires and an additional 3 inch body lift and I am wondering what gear ratio and what not I would need to upgrade to? 4.10, 4.56, 4.88? All help is appreciated Thanks!

I run 37x12.5R17 with 4.88 gears. I have no issues in deep mud or long trips on the highway.

Just as a side note theirs no real right or wrong answer to this, it comes down to preference, but I think most will say that 4.56 or 4.88 will be good for that tire size.

Most people are saying 4.88 ill probably go with that. Juat to ask do you know how much that usually costs ballpark range?

I cant remember how much I paid for front and rear sorry.

The other thing you may want to look into is some kind of power chip that can correct your speedo. When I had my gears done I did a K&N cold air intake and a edge power chip at the same time.


I went out about a month ago, and found a Toyota TRD stuck in the mud. He asked if I thought I could make it through the same spot he got stuck. The TRD was probably on like 33's. With 4x4, my 37x12.5R17 BFG KM2's and 4.88 gears I powered right on through his spot with no issue.Click the image to open in full size.

Maybe it's not as bad as I'm thinking it'd be but won't 4.88s be a bit much at highway speeds rpm wise it seems like it'd be getting up there
