Fluidampr Internally Balanced Steel Crank Pulley - K-Series Engine

Fluidampr offers the highest quality harmonic dampers on the market for the Honda K-Series. Torsional vibration can be very destructive to your motor. From the factory most manufacturers use rubber to balance the dampers at specific frequencies. This works well on stock cars, but as soon as you modify the motor or the rubber deteriorates it is no longer tuned to the correct frequency and can cause a lot of damage. Fluidamprs unique gel infused dampers are capable of controlling the frequency of the crankshaft at any frequency which makes them the go to damper for racing teams everywhere!

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. Timing marks - every two degrees from 50° BTDC to 10° ATDC with additional marks at 90, 180 and 270. Meets SFI 18.1 specs.
