Pulleys - 6-Rib Nose & Crank

6-Rib Nose & Crank Pulleys

The pulleys in this section are for 1994-2005 Mazda Miata supercharger kits. These are 6-rib pulleys and were designed for the MP62 based supercharger kits which use a combination of nose and crank pulleys and feature an independent belt to drive the supercharger. These kits utilize either an automatic belt tensioner, or in the case of earlier generations, a "static" 6-rib idler pulley.

All of our 6-rib nose and crank pulleys are CNC machined from billet aluminum. Each pulley is precision machined to the tight tolerances required for proper fit into the Miata's crank pulley or the shaft of the EATON MP62.  As always, proper tolerances for sheave and groove dimensions have been engineered into the design for proper function with v-ribbed belts.

Finally, the pulleys are then treated to a black hard anodized finish. This finish not only serves as a protective finish, but also provides an aesthetically pleasing touch to your engine bay.

Please select the size of pulley you desire to see pricing. Be advised that not all pulley sizes may be available. If the size you select is out of stock, you will be prompted to "Contact us for future availability of this size."

If you're changing your kit's current crank pulley then you may also choose to have replacement bolts and lock washers included with your crank pulley order or you may choose to re-use your original bolts. The bolts provided are class 12.9. 

NOTE:  All of our MP62 superchargers come pre-assembled from Magnuson with our nose mount brackets and a 65mm nose pulley installed. Magnuson seals not only the nose housing of the supercharger, but also the nut securing the nose pulley to the supercharger. Changing nose pulleys, thereby breaking the seal, may result in Magnuson denying future warranty claims should you ever need to submit for one.
