Fluidampr Harmonic Balancer - 7.3 Powerstroke 1999-2003

Fluidampr 720211 Harmonic Balancer Upgrade

The upgraded balancer 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. The Fluidampr smooth the engine at high RPM levels reducing stress on the internals of the engine. Not to mention a smoother idle around town. A must have upgrade for stock or modified engines. This twisting action is known as torsional vibration. Torsional Vibration is what the Fluidampr is designed to control no matter what power level your 7.3L Powerstroke produces.
