replace my blocks for air ride.

[OBSboy]

i have blocks and leaf springs on my truck right now a total of i think 8" and the ride is almost like rideing a wooden wagon on the oregon trail. does any one know were i can find 4"-6" air ride lift kits for our trucks? ive had no luck so far and i dont wnat to spend $2000 on a super awsome custom air ride system. (but that be pritty awsome if i could)
