Guardian electromagnetic fan clutches have been engineered with a stronger, more precise magnetic flux, which provides consistent engagement throughout the entire life of the friction material. Designed as a direct OEM replacement for 996158, 986158 Fan Clutch Horton.
2 Year/200,000 Mile Warranty
GUARDIAN is our electromagnetic fan clutch.
Kit Masters has engineered a stronger, precisely targeted magnetic flux that remains effective throughout the entire life of the friction material. Through decades of innovation we have engineered the industries best fan clutches.
MAGNETIC FLUX is the force that engages an electromagnetic fan clutch.
The amount of magnetic flux required increases as the friction material wears. Competitor’s designs have enough magnetic flux when the friction is new, but not when the friction is worn, which results in slipping and eventual failure.
Kit Masters has engineered a stronger, precisely targeted magnetic flux that remains effective throughout the entire life of the friction material.
Our R&D department operated these fan clutches in an environment that rigorously tests the number of engagements & disengagements before failure. Kit Masters’ electromagnetic fan clutches lasted more than TWICE as long as the competitor!
Every Kit Masters electromagnetic fan clutch is backed by Kit Masters’ rock-solid, unmatched 2 year / 200,000 mile warranty.
