These are the individual crank pulley rings used with our Interchangeable Crank Pulley Kit for the GM LSA engine.  If you have a Metco 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 the idler relocation bracket and the 50mm idler pulley.  These items are listed elsewhere in this section.
