Power adders, cams and higher RPM change how a EcoBoost crankshaft vibrates, and the stock elastomer damper was only tuned for the engine as delivered. This Fluidampr viscous damper controls torsional vibration across the entire RPM range, so it keeps protecting the crank however the build evolves.
