Description:
Derale Heavy Duty Flex Fans provide maximum airflow at low RPMs when the vehicle speed provides little or no airflow through the radiator. At higher RPMs, the vehicle speed provides ample airflow and the fan blades flatten out to minimize engine loading, increasing horsepower and mileage. Fan spacer and nose cone kits sold separately.
