Trailer Skirts for Commercial Trailers

Trailer skirts — also called trailer side skirts or aerodynamic skirts — are aerodynamic panels mounted along the underside of a trailer’s sidewalls that help improve airflow beneath the trailer. These skirts reduce wind resistance (aerodynamic drag) under the trailer and improve stability at highway speeds, which can lead to real fuel savings and better efficiency — benefits that matter for long-haul and heavy-use applications.

What Trailer Skirts Do

Trailer skirts do:

• Reduce aerodynamic drag by smoothing airflow under the trailer, which reduces turbulence and energy loss at speed.
• Save fuel — fleets will see fuel savings through reduced resistance, especially on long highway routes.
• Improve stability by balancing airflow around the trailer body.

These benefits not only lower operating costs but also reduce emissions and driver discomfort during highway travel.

Trailer skirts are part of aerodynamic trailer design and have been included in EPA SmartWay verified technologies to reduce fuel consumption and emissions for commercial vehicles.

Trailer Skirts for Heavy-Duty Use

Custom Truck One Source offers a range of trailer skirts for commercial trailers and heavy-duty service equipment. Designed to fit various trailer sizes and applications, these skirts are built with durable materials that can withstand daily use, highway speeds and rough road conditions.

Choose Your Trailer Skirt

When choosing trailer skirts consider:

• Trailer length and configuration — make sure the skirt panels match your trailer’s undercarriage span.
• Material and durability — heavy-duty construction resists cracking, corrosion and damage from road debris.
• Installation and mounting hardware — proper fitment that secures skirts to the trailer frame.

Product specs — including dimensions and fitment guides — help you choose the right skirt system for your trailer.
