Kit Masters announced an addition to the GoldTop family of fan clutches with the release of its new two-speed GoldTop.

In standard, over-the-road applications, trucks receive a large amount of ram air through the radiator, which helps in lowering the coolant temperature, according to the company. In a vocational application, where the vehicle is often stationary, there is not the same luxury of ram air and therefore the fan clutch is required to run more frequently to help lower the coolant temperature. This increase in fan clutch engagements can lead to poor mileage, excess noise and, ultimately, premature fan clutch failure, added Kit Masters.

The purpose of the two-speed GoldTop is to reduce fan clutch engagements, while still providing adequate cooling, noted Kit Masters. Through the use of a viscous fluid chamber, the two-speed GoldTop is able to remain partially engaged while drawing almost no horsepower from the engine, said the company. This partial engagement provides continuous cooling and therefore a full fan clutch engagement is required less often. This results in less noise, better fuel mileage and more consistent operating temperatures. Also, fewer engagements means less wear and tear on the fan clutch.

Kit Masters’ two-speed GoldTop is available now as a rebuild/conversion kit and is available on Kit Masters’ remanufactured fan clutches. For more details, be sure to visit the Kit Masters website.
