With a new Canadian distributor announced at the same time, SmartTruck has introduced the second generation of its UT-6 Trailer UnderTray system. In production now, the new version is said to be more durable and versatile while still delivering a fuel-efficiency gain of more than 10%, according to test results.

The new version is much more adaptable to fit a wider range of trailer models, the company says.

SmartTruck’s new Canadian distributor is Winnipeg-based Northern Aerodynamic Solutions.

The new UT-6 UnderTray system includes redesigned components that are higher off the ground and allow the ‘sled’ to be independent of the suspension system. The redesigned system also reduces the size of the rear diffuser, allowing the suspension system to travel to the full rearward position.

The redesigned components, along with a more universal hardware package, combine for easier installation on a wider range of trailer models, cutting installation time to less than two shop hours per system.

Along with increased fuel efficiency, a secondary benefit is cooler operating temperatures around the brake, tire and wheel assemblies due to increased airflow under the trailer.
