3800 Modular Pulley System

The pulley system includes HUB, pulley of your choice, 5 stainless socket cap button screws, and one barbed retainer to replace the breather bolt.

After removing the stock pulley our steel hub presses on using the same pulley tool used to remove the factory pulley. No jaw style puller should be used to remove a supercharger pulley. If it is used, it will destroy the pulley and possibly damage the supercharger.

Once installed, the hub allows quick changing of pulleys with an Allen wrench. The ZZP MPS allows you to change between pulleys depending on conditions - use one pulley for street use and a smaller for the track or when running high octane fuel. A modular pulley system is a must for those planning to continue to modify their car in the future.

Our pulleys come with 8 ribs on them, but a 6 rib belt will still work completely fine.

Great fit, easy installation

Looks good and was the correct size. Having the ability to switch pulleys easily is a great asset

M90 3 inch pulley

I received the pulley and it looks great. Am installing water/methanol injection first, and then the pulley. Intend to increase boost at lower RPM for improved driving experience. Will never race it. We are talking 4500rpm or so tops. Will let you know how it comes out. G.C.
