Powerbond PB2221SC Supercharge, Performance Harmonic Balancer

PowerBond Supercharger Performance harmonic balancers are designed for high performance supercharged engines with high-pressure bonded dampening runners for maximum torque resistance. They feature twin key ways for secure crank mounting and their design is SFI 18.1 approved.

Dayco POWERBOND Street Balancers are also perfect for limited spec race classes such as late model stock that require an OEM style balancer.

The bonded dampening rubber in every Dayco POWERBOND Street Series balancer eliminates spinning and component separation giving reliable performance in engines used to 6500rpm.

Dayco POWERBOND Street Series combine new high strength SG (Nodular) Iron balancer centres with new inertia rings, bonded then balanced to extremely tight tolerances.
