Just to let you know when you put those snap pins on you have it backwards the first time.. turn it around so the rounded edge of the pin is facing the truck that way if your tire kicks up a rock and it hits the snap pin (and it will) it wont knock out the pin and have your hook come off. Could be very ugly. Great video.
