SBF 6.375 in Steel Harmonic Balancer - SFI

The PowerBond Race Performance Harmonic Balancer PB1479SS is designed for high-revving and high-horsepower street/race applications, particularly for Small Block Ford (SBF) engines. It is SFI-approved and tested beyond 21,000 rpm without failure. This balancer features a precision CNC-machined AISI 1045 forged steel hub bonded to a strong steel inertia ring, offering a lightweight design similar to original cast iron balancers. The steel inertia ring is protected against movement, and it utilizes a high-pressure, low-cure natural rubber developed in-house. It includes easy-to-read computer-etched timing marks and meets SFI specification 18.1. This premium OEM replacement balancer is suitable for serpentine and V-belt drives, manufactured with ductile iron casting and injection bonded dampening rubber for superior bonding strength.
