Just lifting the body or suspension too? I don't have a body lift, but I do know others who have done this, basically putting spacers in between the mounts to the frame of the truck. Just remember there are a few things that may require modifications, or relocation, bumpers, stick shifts, possibly some under hood components. I wanted to do this to my truck but our local laws here are so vague about body lifts, and everyone I've asked had a different answer about the legal height that I just gave up on the idea. Hope this helps a little.
