Our ProCharger pulleys are cut to .001" accuracy and properly shaped for maximum belt-to-pulley contact. Then these pulleys have the Sur-Grip coating applied to lesson belt slip even more. Sur-Grip is a tungsten-alloy granular coating applied into the vees of the pulleys with a process called Electrofusion. This process creates a true metallurgical bond with the pulley and very high bond strength. The granular surface allows the rubber in the belt to "key" into the pulley, greatly increasing its tractive force. In addition to increasing the surface friction for the belts, it also increases the surface hardness of the material up to 72Rc, making the pulley itself more durable also.
