I love how this wheel alignment kit has changed the look of my truck! Installation wasn't easy, but they did it in the garage in about 5 hours. Two trips to the hardware store for outlets that I didn't have don't count. Unfortunately, a second trip should not have been necessary. I had to go back for a 17mm deep head to attach the spacers to the post. The instructions said 16mm so I bought it for the first time and had to go back for 17mm. There are several videos on YouTube on how to do this, but this is the best I've found, titled "How to Install an Alignment Kit on 2014-Current". Silverado. He made sure of all the unexpected scenarios I encountered. Bigger tires could have been used, but I stuck with stock wheels and 275/70R18 BFG AT KO2 tires. I love the look! The truck appears much more powerful, but not intrusive. I'll update if I run into any issues, but for now I'm rating this one 4 stars. I'm not giving it 5 stars just because of the wrong instructions.
