Crank Pulley Ring

2009 & Newer Cadillac CTS-V, 2012 & Newer Camaro ZL1

These are the individual crank pulley rings used with our Interchangeable Crank Pulley Kit for the GM LSA engine.  If you have our kit installed on your car, you can buy the rings separately for a quick and easy change to the boost level.

These crank pulley rings are precision-machined from billet aluminum, and black-anodized for long-lasting good looks.  The ring dimensions listed are as measured from belt surface to belt surface.  These measurements do not include the flanges of the pulley.

Please note that 9.10" and 9.55" rings require the use of our 50mm crank idler pulley, and that 10.00" & 10.50" rings require the use of our idler relocation bracket and the 50mm idler pulley.  These items are listed elsewhere in this section.

Each ring size will require the appropriate supercharger belt.  If you have questions regarding belt size, please call or email ( for assistance.

Please choose from the available sizes below.

The 8.60" and 9.10" pulley rings can be used on the 2016 & later LT4 applications using the appropriate Innovators West balancer, PN 8410.  Fitment of ring sizes 9.55" and larger may require modifications and/or additional parts. 

Note:  These crank rings can also be purchased in a 10-rib configuration for custom applications.  Please call or email for details on availability and pricing.
