Product Description

The Fluidampr 570809 is a high-performance viscous harmonic damper designed to control crankshaft torsional vibrations in demanding engine environments. Unlike traditional rubber-bonded OEM dampers that degrade over time, this unit uses a sealed silicone fluid inertia system that continuously adapts to changing engine harmonics across the RPM range.

This technology helps reduce stress on internal engine components such as crankshafts, bearings, and timing systems - especially in high-torque diesel and performance applications. The precision-balanced steel construction ensures long-term stability and consistent damping performance under heavy load conditions.

Because this is a universal-style performance damper, proper fitment depends on correct crankshaft dimensions and application-specific setup. It is commonly used in upgraded or modified engines where OEM damping is no longer sufficient for increased vibration loads.
