If youn look at airride they have the kit for the front. I believe thats under the coolride section and it is $524. As for the rear you can have a few things. You can have air over leaf which is
this andits $324 or you have the
4-Link setup from airride which varies in price. As for compressors and all that airride has the new
ridepro system which looks real promising. I believe I priced everything out with my local tire store and buying everything (front kit, 4 link, and the 3-5second ride pro system) and installation was $2500 installed but thats with my discount and help. So your looking at $2000-3000 for a full air suspension or more. If you just wanted air bags without the compressor and stuff then that would cost you under $1000 if you went with air/over leaf. If you have the money I would go with the 4-link though.
