The Fluidampr 720211 High Performance Diesel Damper works on 1999 to 2003 Ford vehicles with the 7 3L Powerstroke diesel engine. The Fluidampr 720211 Harmonic Fluid Damper will increase the horsepower and torque of your motor while saving your crankshaft. The effective control of the destructive torsional vibrations allows your motor run smoother, quieter and longer. 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.
The Fluidampr 720211 Harmonic Fluid Damper eliminates the torque spike which occurs each time the air/fuel mixture inside a cylinder is ignited. This torque spike is so severe that it not only turns the crankshaft, it actually twists the crankshaft ahead of its normal rotation and then the crankshaft rebounds. This twisting action is known as torsional vibration. Torsional Vibration is what the Fluidampr 720211 is designed to control no matter what power level your 7.3L Powerstroke produces.
