High performance diesel engines running chips and programmers are exceptionally vulnerable to torsional vibrations. Save your crank & more by installing a new Fluidampr 870201 Harmonic Damper today on your 6.0L Ford Powerstroke. Each time the air/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 regular 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.

Fluidampr 870211 Harmonic Dampers are designed to control those destructive vibrations in the 6.0L Powerstroke diesel engine at all engine speeds and power output levels.

NOTE: This Ford Powerstroke Fluidampr Harmonic Balancer is for the 2003 to 2009 Ford 6.0L Powerstroke diesel engine with a Single Alternator.

  • FAQDo I really need to change the crankshaft damper on my 6.0L Powerstroke diesel engine?  The harmonic damper is considered a wear item and needs to be replaced over time. If you have changed the power level of your 6.0L diesel engine, we strongly recommend the installation of a Fluidampr performance diesel damper on your engine, as the OEM damper was designed for stock power levels only. Why should I purchase a fluidampr viscous damper for my engine? The Viscous Performance Diesel Damper for 6.0L Powerstroke Diesel Engine provides control of the destructive torsional vibration on a stock or modified engine. The torsional vibrations present a higher risk for damage, so a viscous damper is an absolute must on these motors. Only a Fluidamper viscous damper protects the engine from destructive crankshaft torsional vibration.
