Ford 9 inch.
 

Will a 9 inch posi fit on my '01?
I really want one but not sure if they make one for "new edge"

Built to order, but unless you're making ridiculous power and launching hard or want to easily swap between center sections frequently, it's completely unnecessary. A strong 31 spline differential and a good set of axles in an 8.8 will do fine for the vast majority of situations. But it's your ride, whatever floats your boat.

Thanks much!
