3.15

Anybody with 3.15 rearend? I'm looking at leftover 15 an that's pretty much all what they have in the Louisiana. How you like it? What size wheels? Whats your mpg? On every expedition forum it seems like everyone has 3.73.

There are a few here with 3.15 gears, they are only available in the 4x2 standard length. The majority of the standard length Expeditions come with 3.31s. Standard length can opt for 3.73s while those are standard on all extended Expeditions. Unless you plan on a lot of heavy towing the 3.15s should be just fine. All wheel/tire options are approximately the same height so tire option does not impact overall gear ratio. Good luck...
