ECOFLAPS from FleetAero are vented splash guards designed to reduce road spray and improve aerodynamics on commercial vehicles. As the only EPA SmartWay-verified mud flaps, they use wing-shaped channels that direct water through a dead-air zone before releasing it to the road, helping limit spray that can obstruct visibility for following traffic. Constructed from impact-resistant nylon polymer, the flaps are resistant to diesel, oil, coolant, salt, and common chemicals, and are tested to withstand extreme temperatures from -200°F to 200°F. The design supports universal mounting and can be trimmed for fit. Backed by a two-year warranty.
