Fluidampr 960311 5.9L Cummins 92-98 Fluidampr Harmonic Fluid Dampers


The Fluidampr 960311 is for the 5.9L 12 Valve Cummins engines produced from 1992 to 1998. The Fluidampr Harmonic Fluid Damper is designed as a direct bolt on replacement viscous crankshaft damper. A new Fluidampr harmonic balancer on your 5.9L Cummins diesel truck will not only protect your engine from destructive torsional vibrations but will also increase Torque, Horsepower and quiet down your engine. A Viscous Damper offers superior control of the crankshaft vibrations when compared to the factory rubber damper. The Fluidamper continually adjusts to provide optimum damping of the destructive vibrations across the engines entire operating rpm band. This damper is on Back Order Until 01/20/2019

Each time the air and fuel mixture inside a cylinder is ignited, the combustion that occurs creates a torque spike that is applied to the crankshaft through the piston and rod. This torque spike is so severe that it not only turns the crankshaft, it twists the crankshaft ahead of its normal rotation and then the crankshaft rebounds. This twisting action is known as torsional vibration. When these torque spikes and forces get into phase with the natural frequency, critical torsional harmonic vibrations occur and can be severely destructive to the bearings and the crankshaft. The Fluidampr 960311 5.9L Cummins 1992 to 1998 Fluidampr Harmonic Fluid Damper is designed to control these destructive vibrations on a stock or highly modified diesel engine.
