Reduce Noise: Made of thermoplastic and steel, and the V-Ribbed structure increases the wrap angle with the pulley, reduces impact contact, absorbs high-frequency vibrations in the engine transmission, and significantly reduces operating noise.
Extend life: The tensioner can effectively extend the life of the engine system by providing appropriate and stable tension to avoid abnormal friction between the belt and the pulley, the chain and the sprocket, and prevent rapid wear caused by looseness.
Improved Stability: The V-type tensioner uses a spring to automatically compensate for the stretching of the belt and chain caused by long-term use, ensuring that the tension is always at the best state to avoid slipping, jumping teeth or falling off.
