Daycos Automatic Belt Tensioner features a patented flat spring design thats engineered to provide less operating range variations in tension. This reduces the risk of premature accessory bearing failure due to high tension when a new belt is installed. It also lessens the risk of belt squeal and slippage, or poor accessory.
