The bump stops are inside the strut (not easily accessible)....
Heres mine for a height comparison:
I'm just fine without bottoming out issues. Are you sure its actually bottoming out and not another component making noise? Do you see rub marks on the top of the front fender liners? I've moved my truck to and from the diveway on the bump stops.... bottoming out would not be easily mistaken. Your truck looks fine height wise.
