SBF 50oz. Steel Harmonic Balancer - Non-SFI

The SBF 50oz. Steel Harmonic Balancer - Non-SFI from Power Bond Balancers is purpose-built for Small Block Ford engines requiring external balance correction. This harmonic balancer addresses a critical need in street and competition builds where factory damping and balance specs fall short of modern performance demands. Whether you're assembling a stroker engine, upgrading an existing platform, or building a high-RPM combination, this balancer provides the inertial correction necessary to extend engine life and improve reliability under sustained load.

Manufactured in steel with black paint finish, the SBF 50oz. Steel Harmonic Balancer features a 6.400-inch outside diameter and carries a 50-ounce external balance specification, making it compatible with Small Block Ford engines that have been internally balanced to half-weight standards. The harmonic design absorbs crankshaft vibration that would otherwise transmit to engine mounts, accessories, and drivetrain components, reducing noise and wear. The Non-SFI designation indicates this balancer is optimized for street and strip use rather than sanctioned competition, allowing for cost-effective performance without certification overhead.

This balancer suits builders working with 289, 302, 351W, and other SBF configurations that demand precision balance correction. Installation requires proper crank key alignment and fastener torque specs per engine manual standards. The 9.82-pound weight and compact footprint (10.3 x 6.05 x 10.6 inches) ensure fitment in tight engine bays without interference with accessory drive systems or radiator shrouds. Professional installation by a qualified engine builder or machine shop is recommended to ensure correct phasing and secure mounting, critical factors that directly impact engine longevity and performance.
