Alberta's temperature swings, from summer heat to deep winter cold, are hard on cheap mud flaps, which is why Rally Armor builds their UR line from flexible, UV-resistant polyurethane instead. Each set includes four custom-fit flaps for the Subaru Crosstrek with stainless steel and plastic mounting hardware, no drilling required. Select your model year range and flap and logo colour combination above. Canada-wide shipping from Flat 4 Offroad in Calgary.
