I checked them on the company's website and the third party's. They fit perfectly on my 2012 GMC Sierra 2500HD with heated and power folding mirrors. The instructions are not very good so I recommend watching the installation video on the company's website, you can't go wrong. They are not expensive but very functional. The adjustment is tight, but once you've adjusted them, they probably won't move (which is a plus). The quality of the mirror glass isn't as good as the original mirrors, but it's good enough to get the job done. And the price makes them a great value. I would buy them again without hesitation.
