Dayco Idler Pulley Fits select: 2011-2019 FORD F250, 2011-2019 FORD F350

Dayco No Slack Idler/Tensioner Pulleys are built with smoother surfaces and tighter dimensional tolerances, which translates to less vibration and therefore longer belt life. Lifetime lubricated ball bearings and double high temperature seals assure peak bearing performance, the most critical element of a pulley's service life. This specific "grooved", serpentine belt driven steel pulley contains a specially formulated e-coating, comparable to OE plating that resists corrosion and wear resistance under harsh environments.
