Dayco Idler Pulley Fits select: 2004-2012 CHEVROLET COLORADO, 2006-2010 HUMMER H3

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. This pulley includes dual Lifetime lubricated ball bearings and double high temperature seals to assure peak bearing performance, the most critical element of a pulley's service life. This specific "flat", serpentine belt driven steel pulley contains a specially formulated e-coating, comparable to OE plating that resists corrosion and wear resistance under harsh environments.
