Our flexible UV-resistant urethane mud flaps are durably abrasion resistant and long wearing. These UR (as in "you are") premium urethane mud flaps are formed for variably high hot and/or low cold temperatures giving drivers 4 corner protection against salt, spray, paint damaging gravel, tar and grime that prematurely wear the vehicle finish away.
