My experience can help you decide I bought my Sierra used in February 2019. I've put 272,000 miles on it and plan on using it just as a means of getting the boat ashore. The jack and tool kit were missing so both were needed. This tool set serves both the jack and the spare wheel jack. My jack's short input shaft is a square with worn/rounded corners that don't provide enough engagement. Because of this, the Red Hound's square end slipped and warped and therefore did not rotate the lift shaft. I think if my jack's input shaft had the original profile this tool kit would work fine, but the tool's steel material is not very hard and can deform with the force required to overcome the jack clutch's resistance. Those things said, here's how I got Red Hound to work for my needs. I've given up the idea of using any tool to work with my spare winch, but have modified it to make it easier to use as a jack. The usual jack method is to use the square hole of the supplied wrench/tire bracket to hook the extension tubes to rotate the jack inlet. The iron hoop method is awkward and wobbly, and carries the risk of body impact during a turn. I applied epoxy to a 3/8" 12 point socket and drove it into the smaller square end of one of the Red Hound extension tubes. Now I can raise and lower the jack with the ratchet, and now I have to mess with one messing around with bulky tire levers. Now a "workaround" repair for your worn spare tire jack shaft. , 13mm, 12-point, deep bushing (epoxy coating inside of bushing) onto square-point input shaft of lifter. Buy 1/4" or 3/8" drive extensions long enough to reach behind the rear bumper and lift it easily.
