  • Balance = Internal

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. 

The Fluidampr 960311 Viscous Performance Diesel Damper is vastly different than your stock rubber-based damper. Only a performance Viscous Damper can effectively control torsional vibrations across the entire RPM range and power output levels. This Harmonic Damper is precision machined in an ISO 9001 facility and then computer balanced for the highest quality replacement harmonic damper available today!
