Kit Masters Fan Clutch

Maintain consistent engine cooling under heavy load with the Kit Masters Fan Clutch. Designed as a remanufactured replacement, this unit addresses common failure points found in worn factory clutches by using an upgraded air cartridge that holds pressure more reliably over time. A 7.03-inch steel back pulley matches the original belt drive ratio, helping the clutch install cleanly without creating alignment or tensioner issues. When operating temperatures rise, the bimetal sensor activates the clutch, allowing the 9.5-inch friction plate to engage fully and pull increased airflow through the radiator stack. Built to support demanding vocational and highway operation, the Kit Masters 91010 fan clutch helps maintain stable coolant temperatures during sustained climbs and high ambient heat.
