There was a guy over at MyBigBronco.com (site is gone now) that made a 1" body lift out of round urethane stock, cut into "pucks". You might find him at FullSizeBronco.com or Superford.org I know of no kits ready-made, so you will have to make your own. I am not a fan of any kind of body lift, but if it floats your boat, more power to ya!!!
