It's been about 6-8 months since my last call so I called Procharger today to ask about the prgress on 4th gen kits. Well they still don't have one but....
if someone with a 09-11 4th gen (HEMI) is willing to take their truck to Procharger's shop in Lenexa, KS they will build the kit. I didn't ask what kind of incentive you'd get but I'm sure it would be pretty good.
If interested they said to give them a call and set up the appointment. Only stipulation is that they want a stock truck.
