Four Seasons Automatic Belt Tensioners

Four Seasons automatic belt tensioners are designed to meet or exceed the original manufacturer's automotive and heavy-duty requirements. Their internal spring design promotes even pressure throughout the life of the tensioner assemblies. Heavy-duty tension springs are used to facilitate quiet, smooth, long-lived operation that provides consistent dampening of the vibration of the arm. Four Seasons heavy-duty cast aluminum tensioner arms are designed to exert uniform force and provide constant correct arm alignment. The pulleys are made from either thermoplastic or steel, depending on the application. A dust cover is used to eliminate the possibility of dirt and other contaminants harming the bearing.
