F150 S-spring part no. ?

I've been reading about the F150 trac-loc S-spring. Does anyone have the part number to that and the number to the standard MN12 s-spring. I've read they are different and are the same. Does anyone really know for sure?

The F-150 spring is Ford p.n. F3TZ 4214 A. It's also included with the FRPP Cobra carbon clutch pack kit, M 4700 C. It is definitely a stronger spring than the regular passenger car piece.
