Fluidampr Oldsmobile 350 400 403 425 455 CID V-8 Steel Externally Balanced Damper

Description

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