UltimateFlap UF 1008 20” Dually Mud Flaps are the best mud flap, mud guard, or splash guard you'll ever own! After years of selling other brands, Ultimate Truck decided to build a better mud flap and offer it to our customers. We back every set of UltimateFlap Mud Flaps with a lifetime guarantee not to bend, chip or break. Made in the USA, UltimateFlap Mud Flaps are made from a premium sand-textured polyethylene that is nearly indestructible, extreme weather tested, and will not sail up while you travel down the road. UltimateFlap Mud Flaps have anti-spray channels to direct rain, snow, road debris back down towards the road and away from your vehicle. For extra style UltimateFlap UF 1008 Mud Flaps come with mirror finish stainless steel weights, adding a touch of class, and setting your truck apart from the rest on the road.

UltimateFlap 1008 Mud Flaps are 20" wide by 24" long, semi-custom designed to fit as a rear mud flap for a wide range of dually trucks. Depending on your vehicle's front mud flap needs, UltimateFlap 1008 Mud Flaps can be easily paired with a set of our 12” front flaps (UF 1002). Drilling may be required for proper fitment on your vehicle, and every pair of UltimateFlap Mud Flaps come as a complete kit with easy to follow instructions and mounting hardware.
