I was actually torn between the BDS and the Zone kits. The installer that I used recommended those two kits, and I was fine with that. It really boiled down to what I wanted and what my budget would allow. I researched and researched for what it seemed like forever. I was originally going to go rough country, and then changed my mind; thought about just doing the level kit, changed my mind again. LOL. But then I kept reading about the Zone kits, and I liked seeing what I was reading and decided to go that route. And the cost difference allowed me to get some of the other things that I wanted, so that is why I went with them. I knew that they had good kits, and that they are like a sister company to BDS. The ride is absolutely amazing so far. IMO, it is as good if not better than stock. Hope that helps.
