Powerbond HB1086SS Race Performance Harmonic Balancer 4 bolt Neutral Internal No Balance. 

PowerBond Race performance harmonic balancers bring the advantages of bonded balancers to high-revving and high-horsepower street/race applications where an SFI-approved balancer is required. They have been tested beyond 21,000 rpm without failure, and every balancer features a precision CNC-machined AISI 1045 forged steel hub bonded to an equally strong steel inertia ring. They are very light and in most cases, they are only marginally heavier than the original cast iron balancer. The steel inertia ring on the Race Series models is positively protected against forward and backward movement. PowerBond uses our Race Series high-pressure, low-cure that features a natural rubber developed in our laboratory. Every model has easy to read computer etched timing marks and meet SFI specification 18.1.
