Looking for more boost your your 2016+ Cadillac CTS-V with a supercharger? Change the ratio the blower spins with one of these lower pulleys!!
LT4 Crank Balancer
Rib pulley ring in selected size
This is the completely Interchangeable Crank Pulley Kit for the GM LT4 engine with pulleys from 8.6 to 10.5". The lower balancer is much lighter than the stock unit allowing for less rotational mass robbing your positive displacement blower of less HP per revolution. If you already have our kit installed on your car, you can buy 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.
