Hi all I have a 2007 f150 and I cannot find out what my gear ratio is. It says it is a #17 witch means 3.31 in the f250 and econoline, but it says noting about what it means in the f150. I know my rear end is a ford 8.8.

There's a variety of applications that gear set was put in. You can verify by looking at the axle tag on the diff.
