It either has 3.31 or 3.55 but it might have 3.73 and then there was the ones that had a 4.10 rear
That doesnt help right.
Its probably easier to look on your door sticker and see what it was manufactured with.
Post the axle code and someone will know what it really is.

Go to your truck and look at the rear diff. The diff will tell you. Or write down your Vin and Google ford window sticker then plug in your Vin and the build sheet will tell you.

It's got 3.73. I was at dealership and they had a print out today on it. So what makes the difference in max tow with 3.73 and non max tow with 3.73.?

Class IV Hitch, tow mirrors, upgraded rear bumper, upgraded trans/oil cooler, and more I can't remember.
