I used to run APs in the front with the bottom 2 out. It works great off-road, but it increased the body roll on the street. Now I'm running APs with all the leafs installed and MCs in the back with all of the leafs in an 85 4Runner and I like the trade off. I think everyone likes things a little different, so it's hard to answer. The rear of the 63s do look like they would cause the shackles to bang into a lot of rocks on drop offs
