Tractor Aerodynamic Kit

The FlowBelow Tractor AeroKit consists of aerodynamic wheel covers and tractor tandem fairings that work together as a complete aerodynamic system to reduce drag and save fuel on the tractor. It addresses the drag-intensive area around the wheels of a tractor’s tandem drive axle. It requires a lower initial investment than trailer side skirts and a 9-month payback is claimed for a typical application.

Installation is said to be simple, requiring just one man who can do the work in an  hour — much less with repeated practice — and with no drilling or welding. The complete kit — four wheel covers, middle fairing, and mudflap fairing — weighs 75 lb, half or less the weight of a trailer skirt, the maker says.

FlowBelow says it designed the Tractor Aerokit using “sound technology and accepted science”. The company had it tested by Texas A&M University and the Texas Transportation Institute in low wind conditions using SAE J1321 testing protocols.

The Aerokit works with or without the existence of trailer skirts and other aerodynamic products, and is compatible with many different wheel and tire configurations, including super singles.

Access to wheels and tires is easy, the company says, because the wheel covers are installed with a patent-pending quick-release system to provide drivers and maintenance staff with tool-free instant access to the wheels. Just push the button and turn the wheel cover to remove it in seconds, says FlowBelow. To reinstall, set the wheel cover over the wheel and turn until the quick release clicks, letting you know that it is securely fastened.

The tandem fairings, fenders, and wheel covers are made of 100% rust-proof polyethylene and remain flexible at extreme temperatures to withstand the impact of foreign objects on the road. All components come with a one-year standard warranty.
