Mounting Brackets are good quality and designed well. I gave it 4 Stars because the hardware kit provided is adequate but I don’t understand why you would use stainless steel split lock washers on a stainless steel flat washer. Besides the extra effort to put it all together when you are contorting your body under the truck. I would recommend using stainless steel nylock nuts and save yourself time and effort installing the mud flaps with this bracket kit.
The brackets and instructions don’t distinguish which one is left or right. Also be prepared to get frustrated and try several methods to finally get them in. If you have long arms or happen to have a truck lift you will probably make easy work of it. In addition the screws that come with it are fragile so be easy on tightening. They break with little torque.
The back ones fit perfectly , but the front pair I have to work a little harder to make fit, but , they are a great after market product for my Ram truck.
