body lift kit

[coggonobrien]

got a question for everyone. when I get to that point with my truck I think i'm going to do a 4inch all spring lift and I'm leaning towards a 1" body lift. Now I don't see a 1" kit in existance and i think I would have a hard time paying for it when I can make it. Do the body lift kits just consist of metal pucks and a longer mount bolt? We have a lathe in the shop at work so I figured I would make a set out of aluminum. Then as far as installation between the frame and the soft mount or soft mount and body?

Thanks!
