Product Spotlight: The latest trucking aerodynamics products enhancing efficiency

ConMet

ConMet says its tractor-mounted TruckWings system automatically deploys at highway speeds to close the tractor-trailer gap, reducing aerodynamic drag. At lower speeds, it retracts to allow full clearance for turning and maneuvering. By managing airflow, the system enhances vehicle stability and fuel efficiency. Designed for compatibility with all truck configurations, including day cabs, sleeper cabs, and even reefers, the TruckWings system helps improve efficiency for diesel, compressed natural gas (CNG), hydrogen, and electric powertrains. It can be installed in under two hours.

The system features an aluminum frame and operates autonomously. Cloud-connected telematics provide real-time data, including uptime reporting, to help fleets track and evaluate performance. TruckWings technology is backed by a five-year/500,000-mile warranty.

FlowBelow Aero

FlowBelow's trailer wheel covers with universal latch brackets simplify installation across multiple trailer makes and models with a one-size-fits-all mounting system. Users need only choose their color preference; the universal latch brackets eliminate the need to specify hub type and wheel offset, fitting any application. 

The manufacturer says that trailer wheel covers deliver fuel savings of 0.81%, equivalent to about 0.5 cents per mile, through improved aerodynamic efficiency. The covers are designed to last the lifetime of the trailer, providing long-term operational benefits for fleet operators and measurable return on investment (ROI).

Installation kits include an optional hub odometer stand that integrates with the latch system, allowing easy access for hubometer readings during maintenance operations. The covers are available through trailer OEMs for new builds or can be purchased for retrofit applications on existing equipment.

Transtex

Edge Elite Aero System+ is a streamlined aerodynamic solution from Transtex that is engineered to boost fuel efficiency across full trailer coverage. Comprising Edge Skirts, Edge TopKit+, Edge Flaps, and Edge Fins, Transtex states that this lightweight, virtually maintenance-free package delivers up to 10.49% fuel savings, or 12.09 gallons per 1,000 miles, equating to about $2,877 in savings per trailer, with a typical six-month ROI.

Its minimal-parts design and no driver interaction reduce operating costs, while installation is quick and payload impact is negligible. Built for durability, the system withstands harsh weather, road impacts, and features materials that resist permanent deformation. Independently tested by MVTS, the manufacturer says it also achieved 7.88% fuel savings (8.88 gallons per 1,000 miles) on corrugated refrigerated trailers—yielding up to $2,832 annual savings per unit.

ZF North America

ZF's OptiFlow TrailerSkirt is a durable aerodynamic solution designed to improve fuel economy and meet industry compliance standards. Built for easy installation and engineered to reduce drag and CO2 emissions, it features a patented one-bolt mono-clamp system and flexible thermoplastic struts that hold up in both hot and cold conditions.

Tested and certified for aerodynamic performance, the manufacturer says that OptiFlow TrailerSkirt promotes fuel savings at highway speeds. Available in multiple lengths and standard black or white finishes, it helps improve efficiency without adding operational complexity. Now available in a compact 115-inch length, the latest addition to the trailer skirt line is said to provide flexibility for a broader range of trailer configurations without sacrificing aerodynamic performance.
