On the Road to a Sustainable Supply Chain

These panels smooth the airflow over the top of the tractor cab, especially when the trailer is taller than the cab. Cab side extenders help direct air away from the gap between the tractor and trailer. Both designs reduce aerodynamic drag, contributing to fuel savings.

Gap reducers minimize the space between the tractor and the trailer, reducing pressure drag, leading to improved vehicle stability and better fuel efficiency.

Smooth, aerodynamic wheel covers are fitted over the wheel hubs on both tractors and trailers. They prevent air from getting trapped in the spinning wheels, reducing turbulence and drag for improved fuel economy.

Trailer skirts are panels installed along the underside of the trailer, between the landing gear and the wheel axles. They block wind from flowing underneath the trailer, reducing drag from the underbody and axles, significantly improving fuel efficiency at highway speeds.

Unlike solid mud flaps that can increase drag, louvered or aerodynamic mud flaps feature vents or a design that allows air to pass through. This reduces wind resistance while still effectively controlling road spray and protecting the undercarriage.

Often called “boat tails,” these devices extend from the rear of the trailer to streamline the airflow. They reduce the low-pressure vacuum wake that forms behind the trailer, significantly cutting down on aerodynamic drag and improving fuel economy, especially at higher speeds.
