Fluidampr's new centering technology design is specifically made for race engines to improve the control of torsional vibrations above 6,000 RPM. This new design is far superior to any elastomeric damper and will allow the crankshaft to be balanced with the Fluidampr installed on the crankshaft. Fluidampr's new patent pending technology allows the inertia ring to remain centered in the housing cavity when the damper is at rest.
