5 Reasons to Consider UnderTray Systems Vs Traditional Side Skirts


SmartTruck has a patented Aerodynamic UnderTray System that provides a unique alternative to Trailer Side Skirts. Designed to reduce size of high drag wake, these solutions provide the greatest amount of drag reduction and fuel savings from a trailer aerodynamic device. Incoming airflow under the trailer is compressed and accelerated through the UnderTray components, pulling the high energy airflow from above the trailer into the trailer wake.

Here are five reasons to consider UnderTrays vs Side Skirts for your next trailer:

1. Increased Fuel Efficiency

With verified fuel savings by U.S. EPA’s SmartWay Transport Partnership, even SmartTruck’s basic unit, the UT-1 System, provides a 5.5% MPG Improvement at highway speeds. This translates to 7 Gallons of Fuel Saved per 1000 miles. For those willing to invest a little more, the UT-6 System with Side Fairings provides up to 10% MPG Improvement or 12.5 Gallons saved per 1000 miles.

With the fuel savings provided with either system most owner-operators or fleets will recover their investment within the first year!

2. Less Maintenance Than Traditional Skirts

The UnderTray System is installed inside the footprint of your trailer high off the ground to avoid contact with steep loading docks or other obstacles. Made of durable polyethylene plastic it is suitable for all weather. Whereas with a blowout skirts can often be damaged, ripped or completely destroyed, these systems are designed to last as long as your trailer.

3. Easier Accessibility

With traditional skirts a driver loses access to the undercarriage of a trailer where spare tires and other parts may be stored. With the unique design of the Smart Truck Under Tray Systems a driver now has complete access to the spacing beneath their trailer.

4. A Bolder Look

Most truck drivers take pride in their equipment. The aerodynamic design of the Under Tray Systems provides a sleeker, bolder look than traditional side skirts which typically become mud stained, rusted or damaged from rocks and debris flying up while on the road. As SmartTruck’s catch phrase proves, they are “Changing the Shape of Trucking.”

5. CARB Compliant Trailer System

To operate in California a fleet is required to meet the CARB requirements for trailers. Whether you decide to use traditional skirts or move to a more modern solution like SmartTruck’s Undertrays, a trailer system for fuel efficiency will be necessary to avoid fines that could be potentially catastrophic. Prime Time Equipment can help your fleet meet California CARB requirements.
