Quality made product, perfect fit, easy installation, and great customer service. Gives a sharp look to my truck, so glad I went with these flaps. Recommend to anyone looking for new mud flaps.

13 inch mud flaps

5 5 1
I recently purchased a set of 13 inch universal mud flaps for my truck. The shipping was much faster than I expected and the quality of the product is outstanding! I had an old set of another brand mud flaps on the truck that were starting to look really terrible - they were rusting and dented and, in some places, the metal had actually torn under the weight of the mud flaps themselves. I don't expect to have any of these problems with these new ones - the high-quality aluminum construction will make all the difference! I'd highly recommend these guys to anyone looking for a fantastic set of mud flaps!
