Our 14″ Wide Rear Universal Mud Flaps With Hydro Graphics Are 14″x24″, and Can be used on the rear of full size trucks, Ford, Chevy, Dodge, Nissan, and Toyota. They come complete with hardware, installation instructions, and twist bracket. Some people like a little smaller look for the rear of the full size truck, but we recommend a 14″ wide on the rear of a full size, and a 12″ for the front. The Mud Flaps are 3/8″ thick with anti-spray grooves on the inside of flap to cut down on highway spray. Good for extreme cold and hot temperatures.
