The FlowBelow Tractor AeroKit™ includes quick-release aerodynamic wheel covers and a pair of tandem fairings installed on the tractor that work together as a complete aerodynamic system to address the complex airflow around the exposed rear wheels of the tractor, reducing turbulence and drag.


The patented Tractor AeroKit System reduces aerodynamic drag and improves fuel efficiency of the tractor by 2.23%, typically providing an ROI for long haul trucking fleets in one year or less. 

FlowBelow Tractor AeroKit fairings are made of extremely durable and flexible thermoplastic polyolefin (TPO) material commonly used in automotive applications. Each kit includes four quick-release wheel covers, which provide instantaneous access to the wheel end via FlowBelow's patented "push and turn" quick-release latching system.

Installation Guide

This guide includes step-by-step instructions for proper installation.


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.
