Does the 2002 Z28 come with an open rear diff or an LSD of some sort?

 

You should have either an Auburn or a Torsen. You can jack up the car and see if you can spin the tires in park, If you can not spin them then you have an Auburn, if one spins one way and the other in the opposite direction then you have a Torsen.

 

Cool, thanks.

What is the difference between the two, other than the above stated differences?

 

i know the auburn is a cone clutch type lsd and is non rebuildable, i furget about torsen
