These are the best mudflaps I found. The install is straight forward no BS, no drilling, fit right over the factory fenders and small mud flap. Other brands I tried were a one size fits most run around waste of time. These line right up and fit perfect. Keeps all the rocks and road grime of the truck. Took about an hour to do all 4.

Install was really easy. I really like that the factory mounts are utilized with these mud flaps. The style really matches with the AT4 package and flows well with the design. I was able to stance the wheels out with 2 inch wheel spacers and still not getting mud/rocks flipping into the side of the vehicle. Nice mud flaps. These are pricey but if they hold up and keep the rock chips down it justifies the price tag.

Mudflaps appear to provide great coverage &  look good however we were missing 3 washers as well as the rear/front flaps were missed marked. Not a big deal on the labeling.

Fit and finish is excellent! Wish they stuck out a little more for my larger tires but they will work perfect when my stock wheels go back on for winter. 22x10 wheels -25 offset, 33x12.5 tires, flaps do NOT rub
