This Dayco 89313 Automatic Belt Tensioner-Main Drive is engineered and built to outlast all other aftermarket belt tensioners on the market. This Belt is built with a flat wire spring that allows the internal tension to be concentric to provide constant tension. Each tensioner is built with the patented Deflected Arm Plate to extend tensioner life by decreasing rotational movement. The spring case is built out of sturdy cast aluminum to resist cracking and corrosion while offering better performance and service life. This tensioner has a locator pin built to withstand the maximum drive demands and correctly locate the tensioner for installation.
