This kit includes our 175MM 4AGZE Crank Pulley, Smaller Belt Tensioner Pulley, and the longer supercharger belt needed.
Our GZE crank pulley is 175mm in diameter for high boost on the GZE. On a bone stock 4AGZE this should raise the boost to around 14PSI. If your engine has a much larger intercooler, you will not see quite so high boost pressure, but you will see much more power!
The keyway boss is 200% larger and reinforced to help prevent the keyway breakout that is so common on high revving 4AG's.
The rear keyway boss on this crank pulley is a larger diameter than stock. This requires the slight trimming of the plastic timing cover on the front of the motor. Trim to the second raised line on the plastic cover.
Available in raw silver or grey anodize.Â
We are currently changing all of our pulleys to a gorgeous grey anodize but can anodize up to 10 pulleys in a custom color for an additional fee
