GREENVILLE, S.C. — SmartTruck has come out with a new TopKit fairing system for dry van and reefer trailers, which mounts to the back of the trailer and provides fuel savings of 5.5% according to SmartWay evaluations.

The company said the new system was designed to be a cost-competitive and nearly invisible alternative to trailer skirts and tails. The TopKit consists of an Aero Rain Guard component that runs along the trailer’s top ear edge, and features two side fairing components on the side rear edges. It weighs just 72 lbs.

“Over the past few years, trailer aerodynamic systems have required fleets and owner/operators to add products that extend far beyond their trailer’s original dimensions, effectively forcing trailer owners to install aerodynamic equipment that can become obstructive and can create unwanted issues,” said Steve Ingham, chief executive officer for SmartTruck. “Our challenge with the TopKit system was to design a supremely effective aerodynamic package that would eliminate the previous issues fleets and owner/operators encountered when applying aerodynamics to their equipment.”

The TopKit has no moving parts and doesn’t require driver interaction. It also eliminates concerns about overheating tires and brakes, associated with trailer underside devices.

“Through the SmartTruck team’s research, design work and our extensive testing, which involved cutting-edge computational engineering simulations, we believe TopKit offers the industry a revolutionary option in aerodynamic design,” said Mike Henderson, chief scientist for SmartTruck. “While TopKit broadens our suite of advanced aerodynamic systems, it follows in the SmartTruck tradition and legacy of developing groundbreaking aerodynamic designs which provide maximum fuel savings and durability while remaining protected by staying inside the footprint of the trailer.”

SmartTruck bills the TopKit system as a standalone SmartWay-verified solution, but it can also be used in combination with other systems such as SmartTruck’s undertray system. More info can be found at
