Decided to list my Saleen/SMS 570 challenger supercharger kit, that came off a 570X. Bought off a local member last year, but decided to go a different route with my challenger instead. Last owner claims the supercharger was making noises, so it will most likely need to be rebuilt. I spoke to Jon Bond Performance last year, and they offer a rebuild service. Looking to get $2500 for everything as is. May consider trades for other Saleen/sms parts/wheels, but would need to be a meet up.
