These crank pulley rings are precision-machined from billet aluminum and then black-anodized for good looks and long-lasting surface protection. If you already have the Interchangeable Crank Pulley Kit on your vehicle, one of these crank pulley rings is all that is needed to change your boost level. Our crank pulley rings are available in several sizes, including an underdrive pulley for use with a Kenne-Bell or Whipple supercharger, a stock-diameter ring, +2 lb, +4 lb, +6 lb, +8 lb, and +10 lbs.
When purchased separately, crank pulley rings do not include the (6) socket-head bolts and ribbed lockwashers used to secure the ring to the pulley hub.
IMPORTANT NOTE: The 10.5" and 11.0" crank pulley rings are intended for custom installations. The user assumes all responsibility for any modifications required for installation, including the appropriate supporting modifications. No boost level data or belt length data is available for these crank pulley rings.
