What was the standard gear ratio, and optional ratios available for the 09 F150 Lariat 4x4s?

I've tried searching but can't find what I want.

Reason I'm asking, is I found a 09 I want, but I was told it has 3.31 gears. Didn't think you could get those in a Lariat 4x4....
I want 3.73 and know that was a option, but 3.31?????

 

According to the spec sheet:
https://www.ford-trucks.com/specs/20...d-f-150-1.html

3.15:1 / 3.31:1 / 3.55:1 / 3.73:1

It appears that the 4.6L 3v motor and the 5.4L could be had with any of the 4 choices.
The 4.6L 2v looks to be just the 3.55 and 3.73

A Lariat SCrew 4wd would be 3.31, 3.55 or 3.73.
Also appears that the 3.15 are only available in 2wd

 

Does the truck have max tow? I can't see a 3.31 on a Lariat 4x4.

 

Thanks for the info.

I can't understand why they'd put 3.31 gears in a 4x4 with a 6 speed transmission.

I thought for sure the used truck dealer didn't know what they were talking about; guess that truck is out.

 

I don't think so, It doesn't have the trailer brake controller.

 

PM me the VIN and I can check it for you...but not until the morning when I'm at the rockpile.

 

Is the truck local? The axle code is on the door if you are close enough to the truck to see for yourself.

 

Then 3.31 is a def. possibility.

 

The axle ratio on this one is a 3.31.

 

Wow, sounds like a nice highway cruiser. But not so nice if you plan on putting plus size tires on that rig.

 

Thanks for clairifying.

Need something I can tow with.

I'm having a pretty hard time finding 3.73s.

 

I'm not as familiar with the packaging of the new trucks, but IIRC doesn't the "off road package" come with 3.73s? I'm sure someone can verify that.

 

I know Fx4s come with 3.73s, but I'm looking for a Lariat.

From what I've found.
3.73s are a option, but come with the max tow package.

 

Right FX4 does come with 3.73, but there is an "off road package" separate from the FX4 trim line that adds the locker and skid plates. I believe that package stacks the 3.73 in there. You should be able to apply said package to the other trims.

 

I've got 3.55's in my 2010 Lariat. Had 3.73's in my '05. I was pretty stuck on 3.73's again until I read somewhere or was told that the 3.55's with the new 6-speed tranny actually have a lower 1st gear than the 3.73's with the 4-speed. Just made a run from S.E. GA to Dallas to pick up a '56 F-100 that my dad bought. Hauled it on a 20' tandem axle trailer of mine. The 3.55's and the 5.4l did great. No power shortage that I could tell.
