Specific Design for the 2017+ Super Duty F250, F350, F450 and F550 Front Flaps Stainless Steel Weights Pre-Installed – UF1017F


The 2017 + Ford Super Duty F250 and F350 now requires a bracket for installation of a full-width mud flap on both front and rear. We have developed stainless steel sheet metal brackets that are unique for each corner. The brackets for the front use existing holes, except for one hole in the fender. The hole is relocated by the bracket that is to be drilled. The stainless steel bolt is isolated by a nylon washer to not contact the aluminum body of the pickup. This part number includes a 12-inch wide x 22-inch-long flap that is predrilled to match the studs that are welded to our bracket. This product will cover all tire sizes with a stock Ford wheel. If an after-market wheel with a significant negative offset is installed that requires a fender flare to cover the tire width, then our UF-1017FL may be the best selection. Comes pre-installed with stainless steel weights.

Ultimate Flaps are constructed using nearly indestructible semi-rigid material. Curbs, rocks and logs will flex the flap, but the mud flap will return to its original position. Extremely cold weather is not a problem for Ultimate Flaps. Our material stays flexible up to -42 degrees below Fahrenheit. Getting built-up snow and ice off Ultimate Flaps takes a gentle kick on the back side. Ultimate Flaps stay rigid but conform to the wheel well of the vehicle without grappling between fasteners. Fender flares on today’s pick-ups are made of molded plastic and attach to the inner fender well. The flare is not suitable to mount mud flaps. Flaps must be attached to the sheet metal that can be 3 inches from the sheet metal of the fender or pick-up box. Ultimate Flaps are ideal for installation with fender flares, keeping a tight fit between flare and flap. The flap can be positioned to give a nice straight line from flare vertically. Ultimate Flaps use a grooved material to direct mud snow and rain down and away from your vehicle and whatever you tow. Ultimate Flaps won’t sail back while going down the road like rubber flaps. Additionally, our mud flaps won’t be torn off by backing up in deep snow. Mud with clay content that builds up won’t make Ultimate Flaps rest against your tires because of the weight of the built-up mud. Ultimate Flaps are great for lifted vehicles — especially those needing additional coverage for larger tires. Ultimate Flaps come with 304 stainless steel plates preinstalled. Plates/weights are attached to mud flaps with stainless studs that are welded to the plate, then torqued with stainless steel locking nuts. Made with pride in the USA.
