Designed as a high-performance replacement for the factory harmonic damper, Fluidampr provides effective vibration control throughout the engine's RPM range for stock, work, performance, and competition applications.\u003c\/p\u003e\n\n\u003cp\u003eUnlike a conventional rubber-based factory damper, Fluidampr uses viscous damping technology that automatically adapts to changes in engine harmonics. This allows the damper to accommodate engine modifications while controlling torsional vibration across a broad and changing frequency range without requiring additional tuning or rebuilding.\u003c\/p\u003e\n\n\u003cp\u003eReducing harmful crankshaft vibration can help decrease wear on main bearings and other critical engine components, improve valvetrain operation, and reduce the risk of crankshaft failure.
