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.
