I have a 2011 5.0 fx2 with 3.55 rear end and axle code 19 non limited slip i want to get a limited slip for it but idk what splines it has. and possible gears too. i have looked but not all that computer savvy to find what i need any help would be greatly appreciated.

Thank you
Daniel

 

Unless Ford has changed them they should be 31 spline axles. You can always call the parts desk at the dealer and ask.

 

I would just call Ford. They can tell you
