I was just offered an awesome deal on a procharger supercharger for my 08 Hemi. A buddy of mine is selling his ram, which had the charger on it when he purchased it a year ago, to his brother and his brother doesn't want the charger. My question is if my stock trans/rear end/everything else needs upgrading if I buy this charger. My buddy doesnt know if anything else was done to his 08 except that it is about 6" higher than mine(massive lift). Any help would be great.

Thanks.

 

The rear end in these trucks is pretty solid, I wouldn't worry about it too much. If you have a limited slip get rid of that thing pronto for a DTT or Auburn. Lower gears would help your transmission a little too.
Transmission I'd say bigger cooler, line pressure booster, maybe a temp guage too.

This is all from what I've read on supercharger/big power adder threads IIRC

 

I take it your buddy didnt buy his truck new? At any rate, I think you will be fine as long as you get the boost low. I think 6psi is max on a stock engine??
