Another option is 4 link, or triangulated 4 link which does not require a pan hard bar. These are a little more difficult to set up and you will need to run coil overs, air bags with them. The coil overs or air bags will probably give you the best ride, but the bolt on leaf kit isn't a bad way to go for a someone who isn't a fab guy.
