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.
