The pulleys can be purchase individually or as a system. Our pulleys only work with our hub system, so if you do not have our hub, we recommend purchasing the full 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. 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.
ZZP vs. our competitor's copy cat pulleys Bolt torque spec is 72 inch pounds.
