    12 bolt Differential ?

     



    I’m trying to make a decision on what kind of differential to run, so what works for you on a street car?
    GM 12 bolt.
    Clutch style posi (Stock or HD after-market)
    Gear type locker (Detroit)
    Worm gear locker (Truetrac)
    Spool
    Open (one tire fire)

    Personally, in a light car, I would run a clutch type posi.

    I have a Detroit in the jeep (dana 60 axles) and it is a bit of a distraction when it locks/unlocks.....gets twichy.

    A spool is not really practical and an open rear differential is an obvious hinderance.

    Well, if $$$$$$$$'s not an issue, Strange Engineering makes a drop out center section that uses 12 bolt gears and posi units (factory or aftermarket) and bolts into a Ford (or aftermarket copy) nine inch housing.

    If buckaroos are a consideration go with a nine inch.

    Either way use a posi unit for the street
