Looking for more boost your your 2009 & Newer Cadillac CTS-V, 2012 & Newer Camaro ZL1?  Change the ratio the blower spins with one of these lower pulleys.  If you would like help matching a size to your needs, see our packages or feel free to email us below.
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.  The 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 10.0 and 10.5" 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 sales@weaponxmotorsports.com for assistance.
