Pulley Spacers for Powerdyne, Paxton, and Vortech®


Fits all Superchargers with a 0.785" shaft (Standard Powerdyne, Paxton, and Vortech®)

Corrects Two Problems:
  1. Many supercharger installs use a high-offset pulley as shown below, and those owners have a hard time locating pulleys in different sizes for their application. With this spacer kit, they can use common and easy-to-find aftermarket pulleys.
  2. Misalignment between the crankshaft and supercharger pulley is a common cause of belt slippage. Check your belt alignment and correct it with this kit to be sure that you get maximum tractive force to stop belt slip!
Easy Install: Two Kits available:

Each kit also includes three steel shims to fine-tune the pulley spacing if necessary. These shims are made from hardened alloy steel and serrated to prevent them from rotating or spinning on the shaft.
