Ford 4.10's/FRPP4.10's Difference?

[340.29m/s]

Ok, I realize I have been posting a lot of n00b questions lately... but atleast they are somewhat different from the usual.

My question is how much different are a set of Ford OEM 4.10's (say, from an explorer) and the FRPP 4.10's? Are they actually the same or are the FRPP's dramatically stronger?

edit: Is there even such a thing as OEM 4.10's or are they all FRPP?

I think there all FRPP

they are the same part number.
the only variation is 3.73 has different PN for FRPP and OEM, but we think it's the same gear as well
