Pulley Spacers for Powerdyne, Paxton, and Vortech®

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

Corrects Two Problems:

  • 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.
  • Mis-alignment between the crankshaft and supercharger pulleys is a common cause of belt slippage. Check your alignment and correct it with this kit to be sure that you get maximum tractive force from your drive belt!

Easy and Universal Install:

  • The large pulley spacer in this kit is made from 6061 aluminum and designed so that you can simply cut it to the length you need for your car. Use the steel shims provided to fine-tune the setup after trimming the aluminum spacer to length. The shims are quality-made from hardened alloy steel, in black finish, and serrated to prevent them from rotating or spinning on the shaft.
