Dayco No Slack Heavy Duty Idler/Tensioner Pulley is designed to replace idler and tensioner pulleys for serpentine drives in heavy duty diesel engine applications. This pulley is manufactured from a high strength powdered metal material to afford wear resistance under harsh environments; and, it features double pressed-in bearings to provide long bearing life despite the shock loads experienced in diesel engine applications. The performance demands of original equipment manufacturers of over-the-road trucking and off-road equipment require a "built for punishment" heavy duty construction, that is why they specify Dayco No Slack Heavy Duty pulleys.
