Those are the aftermarket rails that have fitment issues.
Apparently they'll work. But, if your particular about fit & finish see how different the 2 rear bends are. That's not all due to camera angle. It seems all their units are like that. Based on the history posted here. Their fabrication jig doesn't match side to side. It's not even close. IMO
Dennis absolutely correct about the rails....they are very poor quality and the people do not stand by their product. I bought a set and noticed the very same issue that Dennis pointed out in the photo, it is very noticeable. Worse yet, the chrome is very poorly done. Do yourself a favor and don't touch them.
