I really did mine the cheap way although its only the rear. My 92 D150 always sat high in the rear, I had add a leafs and air shocks because I used to tow with it. I no longer use it for towing so I took out the add a leafs and the air shocks, put in the B body Ranchos I had in my Dart with the S/S springs and just bought a set of long shackles and it lowered it about 2-3 inches, I also clamped all the leafs in the front section and installed a set of $20 swap meet traction bars which helped with traction as I race it occasionaly.
