This is the GripTec pulley and hub for the S2000 Science of Speed 1200 Supercharger in 3.0"


This is the most amazing pulley we've used. With 25+ years of supercharger and serpentine belt experience, this is a game changer.


Belt sliping issues are a thing of the past.


This includes:


3.0" Pulley and Hub

HD Green belt


This is a direct replacement for your kit pulley. Once the hub is installed, changing pulleys is

much easier. By removing the 6 Allen bolts you can option other sizes.


With the supplied pulley and belt, slipage is a thing of the past.


With countless runs on the dyno and witnessing how much belt tension is required to maintain boost to reline, we were blown away with this combo.


Be running less belt tension, there's less wear on the belt, supercharger, idler and tensioner pulley.


This the smallest safe pulley  size to run on your NOVI 1200 Supercharger. ( With  kit crank pulley)


Also available:


3.0" Pulley and Hub only


3.6" Pulley and hub only
