Fluidampr Crank Pulley Steel Internal Harmonic Balancer – 6 3/8inch O.D. | 1991-1998 1G / 2G DSM (630701)

You can’t feel them or hear them, but harmonic vibrations are at work inside EVERY internal combustion engine. That’s not good. Similar to glass-shattering forces created by a high pitched note, harmonic vibrations cause metal fatigue and can cause significant power loss because crankshaft harmonics are transmitted to the camshaft and valvetrain. Control this power-robbing force with a Fluidampr harmonic damper that uses race proven vibration damping technology. A high viscosity silicone fluid surrounds a nylon-coated inertia ring inside a laser welded housing. All dampers are coated with a black zinc chromate finish for increased corrosion resistance.
