Andersen Flaps Eco-flaps splash guard line offers the addition of a splash guard that can be paired with wide-based tires and is 18" wide. Its design reduces wind resistance to improve highway fuel economy and reduces excessive road spray by redirecting airborne water to the pavement rather than into passing or trailing vehicle’s lines of sight. This new size of Eco-flaps splash guards is manufactured of the same durable, high-impact nylon as all Eco-flaps. This high-grade nylon enables them to withstand extreme conditions.
