This belt tensioner boasts a high-strength cast aluminum body designed to keep contamination out and resist cracking, fatigue, and deformation. In addition, the advanced material used reduces weight when compared to regular belt tensioners, while also providing added strength and durability. The Dayco heavy duty belt tensioner features multiple patented components which are engineered to handle the higher torque and power pulses exerted by modern diesel engines. FleetPride is your First Click in Heavy Duty®.
