First off --the newbie would like to say hello to everyone. 
I drive on some rough roads and the factory shocks can't keep up even at slow speeds. I want to put on new ones probably Rancho9000s. I also want to install a leveling kit but I can't do it right now. The question is will shocks designed for 0 lift work with a leveling kit later? (I don't want to have buy front shocks twice) They sell 0" lift shocks or shocks for a 2"-4" lift. Are the leveling kit exactly 2"? This may be a dumb question but are the factory height shocks considered 0" to 2" lift since the only other option is 2" to 4" lift?
I am in the Air Force and live in England. I would rather go ahead and install the leveling kit and shocks at the same time but my truck is to long for the alignment racks and they don't have the specs anyway but If anyone knows where I can get the truck aligned overhere I would appreciate it.
