The K&N Super charger works on a libby right? or does it cause you to need to up grade more than its actully worth in the long run.

I'm not an expert (nor have I done any real research), but I've heard that something in the libby's 3.7 cannot handle a supercharger. I hope that helps

Are you talking about the Aircharger? If so, then they do have one. The part # is 63-1103.

K&N does make an Aircharger kit for the liberty, and many people have been using that without issues. A supercharger, on the other hand, manufactured by anybody, is not available for the Liberty, as the piston rings just can't handle it. As far as i've heard, the piston rings are a few thousandths of an inch closer to the top of the piston than usual, and when you start putting in boost, you get blow-by, or similar issues i think.
