Here is a small write up we did on the Griptec pulleys: GripTec Supercharger Pulleys
If you need a certain pulley and do not see it listed on our website, please do not hesitate to send me a message or give us a call.
I have a Reichard 3.0 and 2.6.....that I love....but that griptec looks nice as well! Good write up and customer service, too.
