A couple of years ago I bought a leveling kit for my 02. It was just some plastic spacers that went over the springs. If the ride I had before was 3/4 ton it went to about a 2 ton ride. I talked to some peolple who know suspensions and suggested that the shocks were topping out so I got a little bit longer shock. Those turned the front into a trampoline. I had those shocks in for a week and I took the whole shebang out.
On the removal it looks like i cracked 2 of the a-arms in the process along with severing both front abs sensor cables
