No Slack automatic belt tensioners from Dayco are perfect replacements for your worn-out, lazy tensioner. Belt squeal, improper tracking, or an accessory that has stopped working completely can be resolved with Dayco No Slack tensioners, featuring "flat spring" technology. This design allows for an increase in torque to be transmitted to the belt when needed, compensating for stretch and wear and maintaining constant tension throughout the life of your belt. Made in the USA, these tensioners are built with tough, long-lasting cast aluminum housings and arms, steel locator pins, and arm plates, and are engineered resins to outperform and outlast OEM parts. Take up the slack with Dayco No Slack automatic belt tensioners.

Better than stock

Used on a GenIII Hemi race motor that revs to 7200rpm. The stock tensioner would get slack and throw the belt when I let off suddenly at high rpm's, like you would do at the end of a 1/4 mile. This Dayco unit is keeping the serpentine belt on the pulleys.
