Third truck I have put a set of these on and this set was the easiest to install, uses all factory hardware with no drilling or self tap screws required. There is no measuring height to make sure they're even just a little bit of adjustment in and out depending how far out you want them to be. Definitely worth the money and do  great job of keeping the paint protected and the running boards clean.

In very happy I decided on these, very well made, a lil pricey but so was my truck. I wanted something to protect my truck from rock salt, mud, and everything in between. Installation was easy, just make sure to step back and look at them before the final tightening to make sure they are square and level.

Great Quality, Easy Install

Overall very happy with these mud flaps.  They are exactly what I was looking for.  They look like they fit the truck well and could of have been factory.  They are not overly aggressive but still protect my truck and trailer well.  Install was fairly easy.  All the washers come in one bag and look extremely similar, it would have been easier if they had been separated but it was not that hard to figure out.

Answer:
The blank stainless flaps are less expensive because there are no licensing fees and with the black wrap flaps the black background is applied by hand so there is more labor involved in producing them.
