The Dayco 89657 Automatic Belt Tensioner - Main Drive is engineered and manufactured to outlast all other aftermarket belt tensioners on the market. When it's time to swap out your failed belt tensioner XDP has the Dayco parts you need. This Belt Tensioner is constructed with a flat wire spring that allows the internal tension to be concentric to deliver constant tension. The spring case is manufactured out of sturdy cast aluminum to resist cracking and corrosion while offering better performance and service life. This tensioner has a locator pin to correctly locate the tensioner for precise installation and to withstand the most demanding drive demands. This belt tensioner features a Deflected Arm Plate that decreases rotational movement and extends tensioner life.

Deflected Arm Plate Decreases Rotational Movement
