PowerBond™ by Dayco Harmonic Balancers

Diesel Performance

PowerBond® by Dayco Diesel Performance Harmonic Balancer

Designed as a high-performance alternative for diesel-powered vehicle applications.

Designed with a unique combination of material and casting, the PowerBond® by Dayco diesel performance harmonic balancer provides the maximum strength and durability of bonded dampening rubber. SFI certified, a high-performance alternative for modified diesel-powered vehicle applications, these balancers are dynamically balanced for smooth operation.


PowerBond® by Dayco Harmonic Balancer

Designed as premium OEM replacement balancers for serpentine and V-belt drives on the most popular passenger car, light commercial and four-wheel drive applications.

Manufactured using a premium ductile iron casting and injection bonded dampening rubber, PowerBond® harmonic balancers offer engine builders and technicians the highest quality replacement to standard OEM balancers, which are typically made with press inserted dampening rubber. Our balancers utilize both inserted and pressure-bonded rubber to provide superior bonding strength between the inner and outer balancer rings, helping minimize spin and dislocation.

Street Performance

PowerBond® by Dayco Street Performance Harmonic Balancer

Designed as a high-performance alternative for vehicle applications with modified engines.

Designed with a unique combination of materials and castings, the PowerBond® street performance balancers provide the maximum strength and durability of bonded dampening rubber. Bringing bonded balancer technology within the budget of every performance street engine builder, each balancer is dynamically balanced for a smooth operation and contains easy to read laser etched timing marks.


PowerBond® by Dayco Supercharger Harmonic Balancer

Designed for high-performance supercharged engines.

PowerBond® by Dayco supercharger harmonic balancers feature an SFI 18.1 approved design that includes twin key ways for secure crank mounting. Also designed with a six pulley bolt hole pattern and a high-pressure bonded dampening runner, it provides for maximum torque resistance. Available with overdrive and underdrive pulleys for maximum boost in supercharged applications.

Race Series

PowerBond® by Dayco Race Series Harmonic Balancer

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.
