A Fluidampr performance damper has three components:


1. Outer housing     
2. Inner inertia ring
3. Silicone fluid

The outer housing is what mounts to the crankshaft.  When combustion triggers rapid twisting and rebounding (torsional vibration), the outer housing and inner inertia ring move in-and-out of phase with each other. The motion of the inner inertia ring through the silicone creates shear which eliminates unwanted vibration.
