spools and detroits are two different monsters as well. detroits are gear driven lockers. it unlocks for turning and locks with a 1/4 inch of twist on one side. a spool has no movement whatsoever and you have positive engagement NO MATTER WHAT. big price difference too, 350-750 for a detroit vs 90 for a spool.ASHURA said:Now, about the clunking noise, are you sure you're not mistaking it for a Detroit Lockers AKA solid spool?
posi isnt exclusively used by fords. chevy used posi decades ago along with many others. its just a spring clutch in between the spider gears and end gears of the shaft.asleepaltima said:posi is the name brand ford uses for limited slip.
