As air detaches itself from the rear of a moving truck, it does so in a turbulent manner. Spoilers minimize this turbulence by directing the airflow so that it stays attached to the truck longer. This in turn lessens the drag the air exerts on the truck.
Bearing this essential function in mind, Good Hood came up with Truck Bed Spoilers that are available in factory-design or custom-design for optimum performance. These spoilers easily install to your truck bed.
