Fluidampr Performance Damper – 8″ OD – Single 3/16″ Keyway | Chevrolet Big Block 396-427ci Engines (800101)

Performance Harmonic Balancer For Chevrolet Big Block 396-427 Engines by Fluidampr

You can’t feel them or hear them, but harmonic vibrations are at work inside EVERY internal combustion engine. Similar to glass-shattering forces created by a high pitched note, harmonic vibrations cause metal fatigue and can cause significant power loss because crankshaft harmonics are transmitted to the camshaft and valvetrain.

Control this power-robbing force with a Fluidampr Harmonic Damper with race-proven vibration damping technology. A high viscosity silicone fluid surrounds a nylon-coated inertia ring inside a laser welded housing. All dampers are coated with black zinc chromate for increased corrosion resistance. Timing marks – every two degrees from 50 BTDC to 10 ATDC with additional marks at 90, 180 and 270. Meets SFI 18.1 specs.
