I know this is an old post, but I loved your green truck (read all 109 pages worth of the thread) and so I just had to ask. I drive an 89 k2500 4wd. It's currently at stock height right now and I am planning on lifting it this summer. Due to being a poor college kid, i'm probably going to be running 33's to save a little money, but I cant decide whether to go with the 4" lift or the 6" lift. Would it be worth it to spend a little more on 6" lift so in the future if I wanted I could throw bigger tires under the truck, or just get the 4" and then maybe add a leaf spring to get the extra 2" later on?
