Dayco Drive Belt Idler/Tensioner Pulley | Without A/C | 11-19 Ford SuperDuty 6.7L Powerstroke

Dayco pulleys are built with precision surfaces and tighter dimensional tolerances, which translates to less vibration and longer belt life. In addition to stamped, forged steel and powdered metal pulleys, Dayco also designs ultra-strong glass-filled polymer pulleys that resist wear and tear. The pulleys include premium lubricated ball bearings and double high temperature seals to ensure peak bearing performance, the most critical element of a pulley's service life.
