Next up is mounting the Hi-Lift jack to the carrier. I simply removed the pin holding the base of the Hi-Lift jack to the shaft and mounted the jack to the carrier. There is a welded bolt in place to line up the jack to ensure a perfect fit. I used the provided 1/2-inch hardware to mount the jack and wing nuts to secure it to the bumper. Wing nuts are used so that the jack can be easily removed on the trail without needing a wrench. As you can see in the second photo, you can lock your jack to the carrier with the aid of a long-neck lock.
