    I wanted to see if anyone can help me with a question on a truck i plan to order. The truck will be a F-550 Supercab, 6.0 Diesel, w/ a 9' Dump Box. For the gear ratio do i want a 4.3LS or the 4.88LS... Would there be a big difference between the two... This truck will be driven as a daily driver and will haul mulch and lighter loads usually. I dont want it to gear it too low so its real slow! Any input?

    I got the wrong gear in my 04 550, 513s I think. Dont need all that gear with the PSD. Your thinking right.
