Dayco No Slack Automatic Belt Tensioners

4.33 out of 5 stars 33 Customer Reviews

Dayco No Slack automatic belt tensioners can resolve belt squeal, improper tracking, or an accessory that has stopped working completely. Featuring "flat spring" technology, these tensioners allow for an increase in torque to be transmitted to the belt when needed, compensating for stretch and wear, while maintaining constant tension throughout the life of your belt. They are built with tough, long-lasting cast aluminum housings and arms, steel locator pins, and arm plates. Engineered to outperform and outlast OEM parts, take up the slack with Dayco No Slack automatic belt tensioners.
