The RC kit is the one that I have installed in my 08 and after getting some the quirks worked out it has been great. When I mentioned quirks it had to do with the sway bar links being to tight causing a popping noise but now that they are set correctly no noise what so ever. Besides making things look better it was a very simple install. But if you haul anything with your truck you may want to look at some kits that offer the spacers and rear lift blocks as a whole kit. After seeing what it does with 12 bags of corn in the rear the backs gotta come up a bit, which will give it some of the rake back for hauling.
