Posi-Trac is EATONS name for their Limited Slip Differntial... GM just happens to use it Ford Calls their limited Slip differnential the TrakLoc.. or as i call useless.... there are SOOOO MANY diffrent types of non-open diffs its not even funny... helical, lockers, spools, clutch, spring.... all kinda stuff.... just remember fords LSD is completly useless for taking turns.... i think that even a phantom grip is better
Doesn"t somebody make an electric locking diff? Seems to me , that would be the cat's pj's. Limited slip on the street, locks like a spool on the strip. I forget the manufacture?
