Overview

The Kenne Bell 8-Rib Supercharger Pulley is a new component designed for Kenne Bell superchargers. This pulley is part of an 8-rib system and requires a specific Kenne Bell Pulley Wrench (Part Number KB-SC3140) for installation and removal. The manufacturer advises that new blower belts need a break-in period of approximately one hour of driving before wide open throttle use, and that the belt should be re-tightened after initial stretching.
Show original supplier description
The Kenne Bell 8-Rib Supercharger Pulley is a new component designed to work with Kenne Bell supercharger systems. This pulley is specifically for an 8-rib belt setup, which typically offers increased belt grip and durability compared to 6-rib systems. Proper installation is crucial, and the manufacturer notes that a Kenne Bell Pulley Wrench, part number KB-SC3140, is required for both removing and installing the pulley. Users are advised to allow a break-in period for new blower belts, recommending against wide open throttle use for the first hour of driving. After this break-in period, the belt will likely stretch and require re-tightening before full performance can be utilized to prevent slippage.
