I've driven my 2020 GMC AT4 HD for just about 2 years now, and its had its ups and downs, but overall I still am in love with this truck, and the more I fix on it, the better it gets. For some reason, GM stopped putting steering stabilizers on their HD trucks somewhere around 2011, and in 2016, they stopped putting the brackets on the trucks at all, which meant if you wanted a steering stabilizer, you'd have to get creative. Luckily @suspensionmaxxman makes a bracket kit that allows you to upgrade and install a stabilizer, so today that's what we're doing, and we'll go over the results with a test drive at the end.
