Stemco has announced that its 50,000th TrailerTail aerodynamic rear tail trailer fairing (boat tail) device is hitting the road. TrailerTail increases fuel efficiency by an average of 5.5% and improves stability and visibility for drivers, according to Stemco. TrailerTail technology streamlines the airflow around a semi-trailer and mitigates the low-pressure suction drag that reduces fuel efficiency and creates turbulence, the company described, adding that every TrailerTail offsets the equivalent greenhouse gas emissions of one passenger vehicle.

In late 2015, Stemco’s new TrailerTail production facility in Longview, Texas, came online to help the company keep pace with demand for its aerodynamic components. In 2015 alone, the company sold more than 13,000 units to over 450 customers, equating to more than 9 million gallons of combined fuel savings, or approximately $18 million.

“We saw tremendous demand for the TrailerTail in 2015, even with lower fuel prices. As the price of diesel begins to creep back up, and fleets begin to put a greater focus on fuel and energy savings, we expect to see even higher sales of aerodynamic solutions like the TrailerTail,” said Bob Montgomery, vice president of the Stemco Innovative Tire and Mileage Solutions group.
