Adjustable Ride Height Shocks and Struts

Hey, well I just solved my carbon fiber problem and now I have another. Well, I am looking for some blow jacks a.k.a. air bags or adjustable ride height setup. I want to install the system in my 96 maxima which is being redone as a street racer. So can somebody suggest any retailer or online retailer that is selling the setup.
