Fluidampr Big Block Chevy Harmonic Balancer Internal Balance SFI

The Fluidampr Big Block Chevy harmonic balancer (also called a crankshaft damper or vibration damper) is an internally balanced, SFI-rated damper. It controls torsional crankshaft vibration in big block Chevrolet V8 engines. It is a viscous-style damper, not a standard rubber-bonded balancer.

Key Features:

• Viscous damping design: A precision-machined steel housing contains a freely moving inertia ring suspended in silicone damping fluid. The fluid absorbs and dissipates harmful crankshaft vibration across the RPM range.
• SFI certified: Built to meet SFI safety specifications for racing and high-performance use.
• Internal balance: Made for internally balanced big block Chevy rotating assemblies.
• Durable construction: The sealed steel housing is built to hold up to the heat, stress and high loads of performance engines.
• No rubber to degrade: The damping action comes from fluid, not an elastomer ring that can age, crack or slip.
• Timing marks: Includes timing marks for setting and checking ignition timing.

A Fluidampr can help protect bearings, the crankshaft and valvetrain components by reducing harmonic stress. It also supports smoother engine operation and engine longevity. It suits street performance, street/strip, marine, towing and racing builds. Several variants are available in this product line. Select the child item that matches your application.
