Airbag suspensions

I have a 2002 Escalade sitting on the Giovanna 23"s. I'm sure if you look at car magazines in the Giovanna ads you can see what it looks like. It rides super high above the wheels though, and i don't like that. What are these airbag things, how much are they, and how do you control them? Do you have to mess with anything else if you get those kits? I really know NOTHING about them and I'm really interested in doing this, cuz it looks akward. Thanks alot.

Airbags can be intrusive if not installed properly.

w/o major susp work, it wont happen for ya...
you have a 4wd, and it is a pain to bag it right. you would have to make a kit for that... and it's been done..
belltech has a 2/3 drop for it... not a bag kit yet though
