Part #: 531101 Fluidampr offers the highest quality harmonic dampers on the market. 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.
