Why use a 2-Speed

In a 2-Speed fan clutch, when the fan clutch is disengaged, the fan still rotates at 15-25% of the engine RPM. This fan rotation provides crucial airflow to the engine and draws virtually no horsepower.

A 2-speed fan clutch is ideal for vocational applications where the fan clutch engagement time exceeds 10% of the engine run time.

Reduce the Frequency of Fan Clutch Engagements

Provide constant air flow without robbing horsepower by utilizing a 15-25% Viscous Engagement. The 2-Speed fan clutch delivers crucial CFM to the engine compartment, keeping a more consistent engine temperature with fewer full fan clutch engagements.

Why switch to 2-speed?

Horsepower Savings

Fewer fan clutch engagements means less horsepower draw.


Improved Fuel Economy

As you recapture your lost horsepower, you improve fuel economy.
HORSEPOWER SAVED = Fuel mileage Earned

Longer Fan Clutch Life

Providing constant cooling means reducing engagement cycles and this will improve the life of the fan clutch, fan belts and belt tensioner.


Driver Comfort

Fewer engagements reduces noise and improves driver comfort.

Lower Under-Hood Temperatures

Lower under-hood temperature is better for the engine and all the engine components.


Easy Installation

With fewer individual components, installation is a breeze.
