Rally Armor mud flaps for Subaru Outback are constructed from polyurethane and designed to perform consistently under diverse conditions. The flexible UV-resistant urethane mud flaps are durably abrasion resistant and long wearing. Providing drivers with four-corner protection, RA Outback mud flaps are crafted for variable temperatures. They help to protect against salt, spray, paint damaging gravel, tar and grime that wear the vehicle finish away. Whereas vinyl and rubber manifest steady, visible material curling and wear over time, strong urethane construction maintains its form through all weather conditions.
