    Welcome to the board. The difference between the ff and the sf is that the ff's axles are bolted to the rear and the ring diamiter is 10.5 inch. And the sf is a c-clip that holds the axle in the houseing and the ring diamiter is 9.5 inch. With 38 i would run with the ff and not the sf. If i am mistaken please let me know.

    Knowledge is the key to the universe, and I hold that key when i am sleeping.[​IMG]

    Once you get up in the size range your past the gray area with a 12 bolt your way past it with a 10 bolt and if your going to wheel it leave the front open and still expect breakage. Really your into the D60 front area of the game or you better get use to replacing axle shafts. 36's is pushing it with the D44/10 fronts and 12 bolt rear.

    It's not my damn planet monkey boy!

    You can break an axle on the FF and the wheel/axle stays with the hub as opposed to your wheel falling off and causing even more problems with the SF,12, and 10.
