This variant is currently out of stock

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.

Fits:

  • Pontiac Grand Prix GTP or 06+ GT
  • Buick Regal GS
  • Pontiac Bonneville SSEi
  • 04+ Impala SS

Have Boost?

This wasn't my first rodeo with this product. I have used this set-up on 3 motors now and it can't be any easier to change pulleys after replacing the stock one. This is a great way to keep adding boost as you make mods to your motor. It will really wake it up! Great investment.

Awesome part and already paying dividends. I had ZZ press on the modular pulley system with my rebuilt M90 snout (which they did for free), and had to pull the pulley to get the coolant reservoir to fit back in. When I'm ready to upgrade to a Stage 2 from ZZ, I'll just unbolt the old and in with the new. Great system!

Easy install. Didn't need to remove the snout to install so that was great. Definitely planning on dripping sizes again. And this makes it so easy.
