SBC 6.75in Balancer Ext. Balance Non-SFI

The SBC 6.75in Balancer Ext. Balance Non-SFI by PRO-RACE PERFORMANCE PRODUCTS is a purpose-built harmonic balancer designed specifically for small-block Chevrolet engines undergoing high-performance modifications. This extended-balance unit is ideal for builders who require precise crankshaft damping without the SFI certification, making it suitable for race applications, street performance builds, and engine swaps where weight and harmonic control are critical.

With a diameter of 6.75 inches and an externally-balanced design, this balancer effectively absorbs torsional vibrations generated at the crankshaft. This is particularly important for engines running elevated boost levels, aggressive cam profiles, or lightweight internal components that can amplify harmonic stress. PRO-RACE PERFORMANCE has optimized the internal elastomer compound and inertia ring geometry to ensure consistent damping across a wide RPM range, preventing harmonic resonance that could lead to premature bearing wear and crankshaft fatigue.

This balancer, weighing 10.83 pounds, adds significant rotational mass without the drawbacks of excessive reciprocating weight, making it a critical component for engines designed for both power and reliability. It is particularly beneficial for those building carbureted hot rods, supercharged street machines, or dedicated track engines. The non-SFI specification allows for versatile applications, ensuring compatibility with various racing and street setups.
