RokBlokz 2017+ Ford F-350 DRW Super Duty Step Back mud flaps are CNC laser cut from a proprietary material specifically designed to endure the harshest environments.

The unique blend of polymers in our mud flaps gives them the specific characteristics that make them highly effective at protecting your Truck and everything you tow.

Specifically the combination of extreme durability, flexibility, lightweight, and rigidity that all come together to allow the flaps to extend out from the fender's edge enough to be effective, to hold their shape at speed and to block the most damaging kind of tire spray. RokBlokz 2017+ Ford F-350 DRW Super Duty Step Back mud flaps will bend, flex, give, and even scrape and drag without breakage. Doesn't matter if you're exploring the frozen tundra or the scorching hot desert, RokBlokz mud flaps will perform.
