Smooth-Side Pulleys for Powerdyne and Vortech® Superchargers with Sur-Grip®

Finally! Smooth-Side pulleys with a solution to belt slip!

If your installation drives the supercharger off of the back of the belt (the smooth side) then these pulleys are for you.

Available in all the common sizes, plus we include our custom Sur-Grip® process to reduce the battle with belt-slip that you have been having. Many report that with Sur-Grip® they are getting more boost than before even if the pulley is the same size.

Fits all Superchargers with a 20mm or 0.785" shaft including all Powerdyne, B&M, CoolCharger and Ford Motorsports superchargers; and Vortech® superchargers.

What Sur-Grip® is: Sur-Grip® is a tungsten-alloy granular coating that is applied to 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.

Choose from these 6-rib Smooth-side Pulleys with Sur-Grip®:

These pulleys are made to the 8-rib format, that is, the width of an 8-rib belt. They can be used on 6-rib installations also. We make these pulleys to order after you place your order. Please allow 2 weeks for manufacturing and Sur-Grip coating.
