talking with a guy (my brother in-law) at our shop today.... who is an ASE cert GM A-tech mech for 20 years and he is a drag racer too. he is trying to tell me that a LSD diff isnt a real posi rear-end... lol i said there are only 3 types of rearends... 1) one wheel peel 2) LSD diffs 3)spool/weld gears. he still insists that there is a true posi and there is LSD diff. i said no there is not but there are difft types of LSD diffs and some work better then others ...felt like i was talking to the front counter help at autozone.... lmao i told him he must of got his ASE cert off a cheerios box :lol:
