Another think to keep in mind is your stock tires are probley pretty worn, and make your truck sit just a little lower then when it was new. So when you measured it, it might have been lower then stock. So you might end up getting more then an inch of height added. Could be two inches. Just a thought.
edit, I just saw you posted this...lol sorry.
