The SmartTruck System delivers durability and fuel performance. I save over $500 a month in fuel. I will only pull a SmartTruck equipped trailer.
Denny Boatman, Owner, Denny Boatman Trucking

Our drivers and owner operators consistently report dramatic fuel savings with the UnderTray System. We were amazed at how easily this was installed. We already placed our order for the next generation side fairings!
We want all the performance SmartTruck has to offer!

We’re seeing our trailer tire and brake costs going down, which we believe is a result of the improved airflow from the UnderTray
