I'm personally going to go with the FRPP differential, I've read good things on it. +1 to the guy above tho too!

the FRPP is the same as the diff in the f150.

I have the 03/04 diff with a TA Performance girdle, held my 660rwhp power just fine.

Look at the Terminator FAQ's posted by Sidecar Jimmy and take "The Red Pill" as posted by Postban you won't have any problems after that. I did and everything is copasetic. Less axle hop. No breakage. Launch at your leisure... Prior to that even my 423hp car broke a cover and halfshaft ! WEAK SAUCE !

Really?

A 4.6 based F150 maybe? :shrug:

5.4 F150 use a 9.75" rearend as I assume the newer 5.0, Ecoboost, and 6.2 Boss F150 do as well.

The stock diff is fine.
