Protect your engine's rotating assembly with the Fluidampr 640901 performance harmonic damper. Factory rubber-based balancers are prone to degradation and are often tuned only for a narrow RPM range, which can lead to component failure as you increase power. Fluidampr utilizes a superior viscous design that controls harmful torsional vibration across the entire powerband, reducing wear on critical engine bearings and oil pumps while minimizing the risk of crankshaft failure.

This damper is precision CNC-machined from high-grade steel and features a corrosion-resistant black zinc finish with permanent engraved timing marks for easy adjustment. Unlike elastomer-style dampers, the viscous silicone fluid inside never requires maintenance or rebuilding, providing consistent, lifetime protection for high-performance builds. Made in the USA and trusted by professional engine builders worldwide.
