There are four boxes for the Rancho kit RS6558-1,2,3,4 Everything you need is in box one and two. Three and Four are the leafs. You can order them separately, heck even Amazon has them. You can get the whole kit however for 2100 shipped from autoanything, JCwhitney will not honor their stated prices and will just cancel your order. I have never had any trouble ordering any needed replacement parts from Rancho through the years for any vehicle, but no they won't piecemeal you a kit together.
