I selling this for a friend. He has a side mount (6 and 8 psi pulleys I believe) magnacharger for a 5.3l with about 40k miles on the unit.

It's currently installed on a 4.8 and is about to be removed today. He decided the truck had too many miles to keep the s/c installed. I'd suggest a meth kit and injectors for maximum gain.
He's asking $2000 obo. (plus shipping)
Pm or call me for any more info.
