I don't know why they don't put these on our trucks as a standard, I don't even know what "package" the tow hooks come in.
But I wanted hooks on the truck, so I order a set brand new from a dealer for $127 shipped on Ebay. The install couldn't be simpler, remove 4 nut, install 2 bolts and re-install the 4 nuts. the worst part of it is cutting the holes in the plastic filler piece in the bumper. I used a small air powered reciprocating saw.
