According to my information, only the 2007 GT500s benefit from this upgraded damper pulley, and the 2007s must use it to maintain warranty coverage when adding the upgraded FRPP supercharger. Not so for the 2008 GT500s.

I called and talked to some guy named Josh,wow.. what an attitude; and I wanted to buy .Oh well.
In quote of my first post.I would like to add ,that I talked with Josh and ;it was a big misunderstanding. I guess some belligerent person called before me, and hung up on him . Then I called.., and I guess he thought it was me. Well that makes sense now. Thanks for clearing that up Josh.
