There are a few ways to do it. It can get expensive if you dont watch it. But for about 3000.00 you can have a nice riding air system that does what you want it too. I suppose you dont want to do alot of suspension mods? Also what size & wheels and tire combo are you looking to run? How low do you want to go?

Remember what you spend on your parts will equal what kind of trouble you will have later. So the cheaper you spend the more problems you will encounter. Trust me I have been doing air ride for a long time here in TN for a living and see it everyday.
