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!

What are you going to be doing with the truck just off road allot of highway or mixed

patclarke

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.

Both its my daily driver but lots of off roading I go every week more then once sometimes.

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

Guys is there also anything else I need to upgrade to run 37s? Any engine work or what not or am I good with just re gearing?

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.

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
