The mounting hardware is very heavy duty. The front brackets are not quite as pictured or described. I ended up drilling a second bolt hole in the front bracket to match the picture, and make the mount function as it should. The metal of the steps feels a bit lite duty, but appears adequate to do the job.
Raptor running boards on 2018 Silverado
These boards are nice looking and fit tight to rocker panel. However it took 5 running boards to receive two that weren't dented. Auto Anything was very good about sending me new ones but still an inconvenience. After two weeks of use, some of the polished "stainless steel" bolts holding the running boards to the brackets started to rust. I had the Laverne boards that look just like these on my last truck that were a little more expensive but better quality. Learned my lesson.
