Jim, Baton Rouge

Reviewed By Joseph C (Baton Rouge, LA) Reviewed for a 2017 GMC Sierra —10/28/2017 6:56 AM

Very satisfied with the color match and overall quality of my LX. Installation was pretty simple and straight forward. I would recommend viewing the you tube vedios. My box came in with a slight tear in the box that upon further inspection found a minor chip in the paint. I used the touch up kit I have for my truck to fix it. Totally satisfied!
