The truck I have is a 2010 5.4. I know they made changes mid 2012 on the Raptor axles. Keith (Wiz1500) told me the changes were limited to the axle shafts and diff pinions (no bearing changes).They are morons... The service guy is looked up parts for 2010-2011 Raptor. They changed the diff in 2012 that is why there are not a lot of options for regearing 2012 and up the last time I checked.. This is from Yukon gear December 9th 2013:
" At this time there is nothing available for the 2012 and newer ford rear differentials. we are in the development process and I will add you to the list for an update when I have one available."
