hi. I have a 2002 chevy extreme and i was wondering what are the chances it has a LSD in it? Did Blazers come with these as an option?

Well, I know that my Bravada has an LSD. I'd have to see your RPO codes (in your glove box - a sticker with a bunch of 3 character alpha-numeric codes). Let me see if I can find a list of the code definitions for your extreme.

thanks for the help
