Special Order Item Crank Pulley Ring Click Here for Damper Fits: 2009-2015 LSA Applications, 2016 & Newer LT4 Applications with Innovators West Balancer These are the individual crank pulley rings used with our Interchangeable Crank Pulley Kit for the GM LSA and LT4 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 on a CNC lathe to ensure exacting dimensions, no runout, and the proper groove shape for maximum belt engagement. Each ring is black-anodized for long-lasting good looks and to provide the optimum surface for the ribbed side of the belt. The ring dimensions shown are effective diameters, as measured from belt-surface to belt-surface. These measurements do not include the flanges of the pulley. In LT4 (CTS-V and ZL1) applications, pulley rings as large as 10.0" can be used without changing or relocating idler pulleys
