I have used add a leafs in the past. They will lift your vehicle but I couldn't say how much. You are taking one leaf and using it to re-arch all of the others in the pack. It works but it will be STIFF. They are cheap and effective, however if you want a good ride save the coins for replacement springs. I have also owned vehicles with a body lift. They work but they create a lot of leverage at the body mounting points. I think the last Jeep I had with a body lift had half of it's body mounts broken. And yes you can combine a body and a suspension lift. No matter what kind of lift you use the center of gravity will be raised. As previously stated you have to drive it like a lifted truck, slow down it's not a racecar.
