High performance diesel engines running chips, programmers, or any other modification that increases your 6.4L Powerstroke power level are exceptionally vulnerable to torsional vibrations. The Fluidampr 800211 Harmonic Damper is designed to control those destructive vibrations produced by the 6.4L Powerstroke diesel engine.

Each time the air/fuel mixture inside a cylinder is ignited, the combustion that occurs creates a torque spike which is applied to the crankshaft through the piston and rod. This torque spike is so severe that it turns the crankshaft, twists the crankshaft ahead of its regular rotation, and then 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. A High Performance Diesel Damper is a smart investment for your 6.4L Ford Powerstroke Diesel engine.

All Fluidampr 800211 Harmonic Fluid Dampers are 100%  Made in the U.S.A.

The only Performance Diesel Damper to put on your Ford 6.4L Powerstroke is the Fluidampr 800211.
