The cost associated to do it correctly is something many over look. Little things will pop up that you were not planning on.
How much lift are you after? What size tires?
If I were you: 6" lift, 35" tires with new wheels for proper offset, 4.56-4.88 gears (front AND rear), longer SS brake lines, possible driveshaft mods, alignment.
That is a quick overview.
