Mud Flaps Available here. Mud flaps are a popular way to customize the look of your vehicle, and can provide that finishing touch to its exterior trim package. However, mud flaps also protect your vehicle and the others around you on the road. Your vehicle’s wings are the main defense against road debris thrown up by the tyres, but they need some help keeping mud, pebbles and stray pieces of rubbish from getting picked up and thrown about. Mud flaps are an easy and affordable way to help keep that debris from scratching and denting your vehicle, and may also reduce the amount of debris that can strike the car behind you.
