Great fit for my '16 Tundra
The bars fit and look great. I'm very happy. No issues with the included hardware. The only issue I found was the instructions appear to have you remove the wrong center bolt (the one closer to the rear vs the front) due to a confusing picture. Just make sure you look at the bars and remove the center bolt closest to the front (CrewMax).

Overall i am happy with my product. Instructions are "ok" at best for installation, they could use an update. The bolts are not a very high grade, i sheared one bolt on the driver side rear bracket. Since they were meant to fit multiple years of my truck it came with alot of extra hardware, that was a little confusing to get started. But once i sorted out what parts i needed installation only took about an hour.
