SmartTruck TopKit Aero System

The smart alternative to side skirts for greater fuel efficiency with undercarriage access and visibility.
The SmartTruck TopKit Aero System, proud to be a two time HDT Top 20 Product (2015 | 2017), is an innovative approach to aerodynamically improving fuel mileage without attaching obstructive components like skirts to the underside of the trailer. With the SmartTruck TopKit, there is no risk of damage from loading docks or intermodal operations and cost is comparable to side skirts.
