This is a replacement pulley for our Modular Pulley System that removes the stock supercharger pulley and replaces it with our stainless hub, and these pulleys will bolt onto that hub. A jaw style puller should never be used to remove a supercharger pulley - if it is used, it will destroy the pulley and possibly damage the supercharger. We recommend using our Supercharger Pulley Puller. 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.

Recommended Pulley sizes (based on 93 octane, 91 add .1, 89 add .3):

  • 3.6" pulley - '04+ Grand Prix supercharged/ '00+ SSEi/ Ultra/ '04+ Monte/Impala SS with ZZP pcm, CAI, cooler plugs/thermostat, and bolt in downpipe.
  • 3.5" pulley for '01-03 GTP/ GS with ZZP pcm, CAI, cooler plugs/thermostat, and bolt in downpipe.
  • 3.5" pulley for '04+ Grand Prix supercharged/ '00+ SSEi/ Ultra/ '04+ Monte/Impala SS with 1.9 rockers, ZZP pcm, CAI, cooler plugs/thermostat, and some exhaust work.

  • 3.4" pulley for '01-03 GTP/ GS with 1.9 rockers, ZZP pcm, CAI, cooler plugs/thermostat, and bolt in downpipe.
  • 3.3" pulley for '97-00 GTP/ GS with 1.9 rockers, ZZP pcm, CAI, cooler plugs/thermostat, and bolt in downpipe
  • 3.3" pulley for '01-03 GTP/ GS with VS/XP cam, ZZP pcm, CAI, cooler plugs/thermostat, and bolt in downpipe.
  • 3.2" pulley for '97-03 GTP/ GS with SS intercooler, ZZP pcm, CAI, cooler plugs/thermostat, and bolt in downpipe.
  • 3.0" pulley requires larger injectors and a full size intercooler or SS intercooler and cam or rocker setup

3.2 pulley

I had already purchased the modular pulley setup. The pulley was so shiny and nice. Such a great finish. It was very easy to swap out the pulley. I loosened the 5 bolts, pulled the belt. Swapped the 3.4 pulley for a 3.2. Just playing it safe. I then installed the 3.2 pulley, snugged the bolts. Placed the belt back on the supercharger and tightened the bolts. Super easy, all the ZZP parts i have purchased are the highest quality. @l67pnw IG
