PowerBond® by Dayco Race Series Harmonic Balancers are designed for high horsepower street and racing applications.
The race series harmonic balancers brings the advantages of bonded balancers to high revving and high horsepower street and race applications where an SFI approved balancer is required. These racing balancers have been tested beyond 21,000 RPM without failure and come in both overdrive and underdrive options. Every PowerBond® race series balancer features a precision CNC machined AISI 1045 forged steel hub bonded to an equally strong steel inertia ring and laser etched timing marks for easy timing changes. Through advanced design, our race series balancers are engineered to be very light for an all steel product. In most cases they are only marginally heavier than the original cast iron balancer, and generally lighter than other all steel balancers on the market. The steel inertia ring on the race series models is protected against forward and backward movement.
This PowerBond® Race Series Balancer is SFI 18.1 certified for high RPM applications.
