What is Crosswind Blocker?


Crosswind Blocker is an easy-to-remove panel system that fills the gap between the tractor and trailer, reducing aerodynamic drag by blocking most of the blow-by from crosswinds. The result is better fuel mileage.


Crosswind Blocker panels are installed on the header of your trailer. With the pull of a pin the panels can be easily adjusted to close the gap between the tractor and trailer.


The Crosswind Blocker system has gone through Real-World testing of over a half of a million miles with an average increase in fuel economy of about 10%.


Whether you are an owner-operator or run a fleet, Crosswind Blocker is designed for you.
