If you have a PP car you can get a loaded diff from Ford but it will have a normal trac lok with the clutches and not the torsen. Cheaper to buy just the gears but more convenient to swap out the whole assembly.Those that upgraded their gears, do you guys get a loaded dif or just buy the gear and have a shop swap them?
Also, going from a roll, how much difference does the 3.55 make vs 3.31?
