Better Than New

Kit Masters’ 8010X is a direct replacement/upgrade for Mack® applications of the HT650® / HT550® fan clutches. The superior design of the 8010X makes for easier and more affordable long-term maintenance. Converting your fan clutch upgrades it from a medium duty fan clutch to a heavy duty fan clutch. Our model is capable of handling a larger fan and will last longer than the competition.
