FlowBelow Tractor AeroKit Information

This vehicle is equipped with an aerodynamic system manufactured by FlowBelow Aero, Inc. The Tractor AeroKit™ is designed to reduce the aerodynamic drag of the tractor and improve fuel economy and reduce rain spray for improved safety. The system consists of three critical components: wheel covers, center tandem fairings and the rear tandem fairings.  

Components | Frequently Asked Questions | Contact Us

 

Component 1 : Quick-Release Wheel Covers

Each wheel cover is attached to the wheel with a ‘quick release’ latch.  The wheel cover can be instantly removed from the latch by pressing the center button and rotating the wheel cover until it is released.  To re-install the wheel cover, push the cover onto the black tabs of the latch and rotate until the wheel cover locks in place.  The purpose of this feature is to facilitate quick inspection and maintenance on the wheel end.   

 

Component 2 : Center Tandem Fairing

This component is located between the drive tires and substantially improves the aerodynamic performance of the vehicle.  The fairing and bracket assembly is bolted to the 5th wheel rail and should not require removal or modification for regular inspection and maintenance.

Component 3 : Rear Tandem Fairing

This component is located behind the rear drive tires and substantially improves the aerodynamic performance of the vehicle.  The fairing and bracket assembly is spring loaded and bolted to the frame rail.  The assembly should not require removal or modification for regular inspection and maintenance.   


In the event that one of the components in the kit becomes damaged and needs to be removed, please store the component in the cab until it can be delivered to maintenance personnel.  In the event that the component needs to be partially or completely removed, refer to the installation instructions for guidance in the removal process.


Frequently Asked Questions

How much fuel will I save? 

The FlowBelow Tractor AeroKit has been proven to reduce fuel consumption by more than 2% through independent, third party tests including SAE Type II fuel efficiency test procedure, wind tunnel testing, CFD modeling and on-road fleet tests. 


How durable is the Tractor AeroKit?

The Tractor AeroKit was designed alongside major fleet partners and is made to standards specified by large fleet mechanics and drivers. The tandem fairings, fenders and wheel covers are made from 100% rust proof polyethylene and are engineered to maintain maximum durability even in known extreme weather conditions and temperatures. 


Does the Tractor AeroKit work with trailer skirts and boat tails?

The Tractor AeroKit works with or without additional trailer aerodynamic devices such as side skirts and boat tails. Because the Tractor AeroKit addresses the drag intensive area around the wheels of the tractor tandem, it reduces fuel consumption no matter what type of trailer you pull. 


Is the Tractor AeroKit compatible with my existing wheels and tires?

The Tractor AeroKit and wheel covers work with most wheel and tire configurations, including super singles.  


Can I easily access my tires when the wheel covers are installed?

The Tractor AeroKit and wheel covers utilize FlowBelow’s patented quick release system to provide drivers and maintenance staff with instant, tool-free access to the wheels. Just push and turn the wheel cover to remove it in seconds. To re-install, simply place the wheel cover over the wheel and turn until the quick release clicks, letting you know that is is securely fastened. 


Can I use tire chains with the Tractor AeroKit?

Absolutely. The fairings provide plenty of access to install and remove your tire chains in winter conditions.
