Made from premium polyurethane, these UR (as in "you are") mud flaps have been engineered to perform consistently in a variety of environments. Our flexible, UV-resistant urethane flaps are durable and abrasion resistant and long lasting. These UR (as in "you are") premium urethane mud flaps are formed for varying hot and cold temperatures providing drivers with 4-corner protection from salt, spray, paint damaging gravel, tar and grime that prematurely wear down a vehicle's finish. Where vinyl and rubber manifest themselves as a stable, visible material that curls and wears over time, the strong urethane construction holds its shape in all weather conditions.
