FlowBelow Aero, Inc., has re-engineered its Tractor AeroKit for improved aerodynamics and enhanced durability. The new Aerokit with Flex Fairing features a more flexible design to increase durability and improve operational performance while still delivering the fuel savings associated with the original Aerokit, first introduced in 2012.
“The Tractor AeroKit with Flex Fairing represents years of collaboration between our engineers, fleet customers and truck OEMs,” said Josh Butler, president and CTO of FlowBelow. “We’ve taken a great product and made it even better, addressing the challenging environments faced by today’s fleets in the real world.”
Key features:
- Durability: The new Flex Fairing is made with a rubber alloy TPE (thermoplastic elastomer) resin, similar to that used in vehicle bumpers. This advanced material enables the fairing to bend and flex under impact, then immediately return to its original shape, making it well-suited for the tough conditions of heavy-duty trucking.
- Improved Bracket Design: All-aluminum support brackets are lighter, corrosion-resistant and repositioned to provide better clearance. The rear mounting bracketry features a 360-degree spring-loaded shoulder joint, allowing for multidirectional flexibility that works in conjunction with the fairing’s more pliable material. (See a demonstration of the feature in the video below.)
- Proven Fuel Savings: Independent testing confirms that the Tractor AeroKit with Flex Fairing can save 3.16 gallons of fuel for every 1,000 miles driven, the company said.
- Extended Warranty: FlowBelow now offers a five-year/500,000-mile limited warranty, five times longer than the previous version.
The re-engineered AeroKit has undergone field testing with 30 to 50 fleets, ranging from 100 to 600 sleeper trucks, since early 2024. Paul Pettit, VP of maintenance, fuel and facilities at Ascend in Jackson, Tennessee, noted the fleet “had a tire blowout on a truck running the new AeroKit, and the entire kit survived the incident unscathed. It was an impressive testament to the durability of the new product.”
Combined with other products in FlowBelow’s portfolio, including the AeroFender and Trailer Wheel Covers, the company said, savings of up to 5.88 gallons of fuel for every 1,000 miles driven, or 2.4 cents per mile, are achievable.
The Tractor AeroKit with Flex Fairing is now available for purchase through FlowBelow directly or can be specified through any mod-center for installation on new truck builds. A video detailing the new AeroKit follows.
