I think it is the control arms and stabilizer bar but not enough of a gear head to remember. All of the "lift kits" include extended and strengthened parts to make up for the change in geometry. Once you would buy the necessary upgrades though, to better support the extra 2 inches you might as well get a 3'' lift kit

Anyways not sure if this explination is way off base or not but it is what is keeping me form putting the leveling kit on my truck. If someone else can explain it better I would love to hear it so I can be more informed. I know the DW was a big concern for me once I started reading about our trucks and moding them.
