Utility Trailer’s new side skirts — the USS-120 and USS-160 — are EPA SmartWay-verified to achieve greater than 4 percent and 5 percent fuel savings respectively. Uniquely, their galvanized high-tensile steel braces are said to be "virtually indestructible" and can simply be bent back to their original shape if damaged. The bracing system allows the side skirt to flex both inward and outward.
Both skirts are created with UV-protected one-piece fibreglass-reinforced-plastic and unique mounting to the support-leg wingplate. They’re CARB-compliant for California operations (the USS-120 as a stand-alone device is compliant for refrigerated trailers only).
The EPA has classified the USS-160 as an “Advanced Side Skirt” which allows truck owners to use them without any other aerodynamic device on dry vans.
Both side skirt designs are now available as factory installed options for new Utility trailers, and retrofitting for existing trailers is available.
