Well I stuck with the original game plan. I got everything installed. I set the preload on the 5100s to the 1/2" setting and used the large preload spacer from the zone kit (it had to be used the way the kits designed if you wanted the preload spacer). With that and the small top spacer included in the kit I ended up with about a 1/2" rake (I have a winch mounted on a brush guard plus airbags in the rear end which slightly lifted the back). I took it for a short test drive and it's actually pretty darn good. I was pretty nervous about the possibility of adding to much preload but the winch weight seems to have acted as expected. Deffinatly noticing how crappy the rear shocks are in that short drive.
