SBF Steel Harmonic Balancer Non-SFI

The SBF Steel Harmonic Balancer Non-SFI from Power Bond Balancers is a precision-engineered crankshaft accessory designed for small-block Ford engines, including the 289, 302, and 351W variants. This balancer effectively absorbs and dampens harmonic vibrations generated by the rotating crankshaft, protecting internal engine components from resonance-induced stress and fatigue. It is built for street and mild performance applications, making it an ideal choice for daily drivers and restoration builds.

Constructed from durable steel, this harmonic balancer features a bonded elastomer ring that isolates vibration frequencies from the crankshaft hub. While the elastomer material can degrade over time, regular inspection and maintenance are essential for optimal performance. Power Bond's design balances performance with longevity, ensuring smooth operation across the RPM band while resisting the heat cycling common in street-driven vehicles.

Mechanics and enthusiasts rebuilding small-block Ford engines will benefit from the reliable vibration control offered by this balancer. Its non-SFI certification indicates it is optimized for road use rather than sanctioned racing, making it suitable for a variety of applications. With a weight of 7.07 lbs, it helps reduce strain on the front crankshaft seal and bearing while maintaining sufficient inertia for consistent damping action.
