I didn't buy them from Revain, I bought them direct from the manufacturer Rigid Industries. I installed them and my truck immediately started squeaking as it drove down the street. I found that the brackets touched the chassis/body cross member of the truck. I had to remove them completely, grind down the contact surfaces and reinstall everything. While not the most difficult to install, it is time consuming and a common problem. You know what to do. All my other experiences with this company have been positive, but I just wanted others to know. I installed them on a 2014 Tundra Crew Max.
