Here, you are looking at the Fluidampr High-Performance Harmonic Balancer. The Fluidampr unit is a torsional vibration damper. It has been designed to provide durability by controlling destructive vibration. As you perform performance upgrades that add more horsepower and torque to your vehicle, you risk overworking your stock engine damper, and changes to your rotating assembly can shift destructive engine harmonics. The Fluidampr unit will provide protection across the entire RPM range and can accommodate future engine modifications without the need to re-tune, and is a proven product utilized and trusted on high-horsepower applications.
