The conversion took a buddy and I 30+ hours (60 man hours). As for lift, my truck sat higher with the RCD kit.
My truck was sitting level when the first pictures were shot, but I only had a couple of inches of down travel left. Once I reduced the preload, the front of the truck is probably 3" over stock plus tire height.
Not really a 4X4 killer. I am just waiting on the half shafts. Aaron was out of stock when my kit shipped out. 4X4 should be up and kicking in a couple of weeks.
I live in Tucson. It will be a while until I can afford to play with the rear suspension, but I will have to chat with 84 to see what his impressions are in regards to the Giant spring pack.
