Let me give u the answer to all of the questions posted. Dont go with the 4" Superlift. If you do, you will need to immediately get new shocks. The Superlift shocks are horrible. Way to stiff. I cant stress enough, too STIFF!
If you do go with this lift and after you purchase new shocks you will need to purchase lca's. Buy the Skyjacker lca's, there alot cheaper than Superlift's and do the same thing. This is what I did.
The only positive thing was that I used the transer case drop and did not have any vibes from day one.
If I had to do it over, i'd probably go with RE
