Silicone performance from Fluidampr.
Using only 3 parts–a laser-welded sealed housing, an internal inertia ring, and a highly viscous silicon fluid between the two–these SFI-approved Fluidamprs can control all crankshaft vibration, not just a limited frequency range. As a result, you get reduced wear on the main bearings and timing gear, more stable valvetrain operation, and less chance of crank failure.
