The rears are more of a problem than the fronts. It looks like in 2011 Ford went to a 37 spline rear pinion from the 35 spline earlier. There were also some internal bearing changes. I can only find up to 4.88 gears with the 37 spline pinion.
But even most of the fronts say 2005-2010... not sure what changed if anything to the fronts.
If you search for 2017+ you wont find much either... again, not sure what, if anything actually changed.

why theres no 5.13 or 5.38 likely boils down to demand. very few people would need such a ratio. for the average joe ( which is most people) ,those high ratios are useless. if they could sell a wharehouse full of them ,they would of made a wharehouse full of them already

that would be great if they made them for the 2017+ which you’ll find doesn’t go lower than 4.88
