The FlowBelow Tractor AeroKit reduces aerodynamic turbulence and drag on the truck by streamlining airflow past the drive wheels. When optioned, each 6x2 or 6x4 truck is outfitted with wheel covers, center fairings located between the wheels and rear fairings behind the wheels. Wheel covers can also be outfitted on 4x2 trucks. The fairing system works like fuel tank fairings by helping to control the air flow along the side of the truck. The ‘Quick-Release’ wheel covers also provide instantaneous and tool-free access to the wheel end via FlowBelow’s patented ‘push and turn’ quick-release latching system. The system is made in the USA using extremely durable materials, the company says.
