  • Overview
  • Specs

Using only three parts (a laser-welded sealed housing, an internal inertia ring, and highly viscous silicone fluid between the two), SFI-approved Fluidampr harmonic dampers 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.
