ok my friend has a hoda civic and thinks hes all badass and knows everything about everything, the kids never gotten his hands dirty. and im not to sure about this but is a possi rear end the same thing as a lsd?? im just wondering thanks guys

 

i believe so.

Positive Traction RearEnd "2 wheels going"

Limited Slip Differential "2 wheels going"

 

Posi IS limited slip. GM was just the company to call it "posi"...

 

well thank you guys

 

GM is Posi-traction
Ford is Traction-lok
Chrysler is Sure-grip

All of these are friction type limited slip differentials.
