Flex-a-lite high performance flex fans are designed to give you maximum airflow at low RPM, and the least amount of engine loading at high RPM. Less resistance at highway speeds equals more horsepower and better gas mileage. WARNING: Must be used with a Fan Shroud!
Use a a fan spacer to position your fan so it is about 1/2 inside and 1/2 outside the rear opening of your fan shroud for the best air flow.
CAUTION: Precision cut fan blade edges may be sharp. Wear long sleeves & gloves while installing or working around these fans.
