Leveling kit void warranty?
You'd have to find out from your local dealer. If the dealer does the install you will probably be fine. I used to do leveling kits on new trucks all the time at a Ford dealership to fit bigger tires on them and they would sell them as "lifted" and they retained their factory warranty because it was installed by a Ford certified tech. But as stated before me, every dealer is different.
Ya, a bunch of dealers here sell them lifted as well. You will see one in every Ford showroom here. For piece of mind/warranty, yes, the dealer-installed option is best. However, they will jack up the price of the truck like you wouldn't believe.
