SmartTruck’s TopKit system consists of an Aero Rain Guard component that runs along the trailer’s top-rear edge and features two side fairing components on the side-rear edges. The system is about one inch thick, weighs 72 pounds and is engineered to provide a SmartWay-verified 5.5 percent highway fuel savings. The standalone system is designed for dry vans, refrigerated units and trailers equipped with either swing or roll-up doors and does not require driver involvement or have moving parts. The solution also helps eliminate increased heating of tires and brakes while reducing damage from dock or intermodal operations.
