*** IN STOCK SHIPS TODAY *** This V-pulley serves two purposes. First it allows mounting of a blower pulley to a harmonic dampner without having to drill the blower pulley to the dampner pattern. It also allows three acc. to be driven off the crank with V-belts. The pulley has a 2.275" register on the back that fits in the dampner as well as a 2.00" male register on the front to keep your supercharger pulley running concentric.
Pulley measures 2.250" thick, has a 5.950" O.D. on the two outer V-pulleys and the inner V-pulley is 5.00" O.D. allowing different acc. to be driven. V-pulley is made from billet alum. that is hard anodized for wear resistance and longevity.
Grade eight mounting hardware is included. This pulley uses six 3/8" mounting holes on a 2.782" bolt circle for mounting of supercharger pulley. Fits 4-71 thru 16-71 roots or PSI screw superchargers.
