basicly here are all your options
Superlift will give you 3-4 inches of lift for about $1200 only bad thing it keeps the T-bars which doesn't bother some people but they do still hang down in the front. Oh and its all bolt in sort of well there is not welding what so ever so its kind of easy to put in.
RCD will give you 5-6 inches of lift for about $2200. More money then the superlift but it gets rid of the T-bars and replaces them with coil overs. Bad part is there is some welding so unless you can weld I doubt you can do this in your driveway.
DBR (dixin brother racing) They make a long travel setup. i think Its something like 14 inches of travel. Its great for pre-runners, and dune jumping. I don't know what they cost but i think it is over $5K
PA body lift (performance Accessories) body lifts are easy to do. Some say as fast as 6 hours. Gives you 3 inches of lift and for only $300.
