Well from many calls and emails, it looks like there is not any, reliable, 4.56 gears available for the 2011+ trucks. From what ive been told, the thread pattern for the 2011+ gears is different due to the fact that they added the elec locking diff.

If anyone has an more info on this please chime in. It looks like i will have to downsize tires in the winter for my towing needs.

Electric locking diff was available in 2010 so that isn't the reason. Ford changed the bearing size in 2011 - it's larger than the 10's.

There are newer Raptors running as high as
4.88 so I'd call SDHQ, Outlaw Raptor or RPG and find out where they are getting the gears made.
