Fluidampr High-Performance Harmonic Viscous Dampers

Fluidampr Harmonic Fluid Dampers For Gasoline and Diesel Engines

A good aftermarket high-performance crankshaft damper protects your crank. Horschel Motorsports' Fluidampr is in a class all by itself because of the over 70 years of viscous damper engineering experience on hand. The Viscous crankshaft dampers are designed to provide maximum control of all the engine harmonic vibrations, regardless of the rpm at which they occur and regardless of the crankshaft's natural frequency. The viscous damper vibration control translates to the maximum protection of the crank, main bearings, engine-related components, and more consistent power output. Also, Fluidampr is maintenance and repair-free. Fluidampr is active in race and street applications because it is a viscous damper that controls the destructive engine vibrations at all RPMs and power levels.

Only Fluidampr produces a vicious-style damper that provides these features:

  • ISO9001-accredited production facility produces the very highest quality damper available.
  • These viscous dampers provide superior durability.
  • Torsional Vibration protection across broad frequencies and multiple engine power output levels orders throughout your rpm range.

The best engine dampers on the market are manufactured in the United States by Horschel Motorsports, an ISO 9001:2000 certified facility. Horschel Motorsports is continuing the tradition that started in 1946 when the first viscous damper was invented. Over 4.5 million viscous dampers have been made for heavy-duty diesel, drag cars, stock cars, street machines, race boats, and other high-performance engines.

The Fluidampr high-performance crankshaft dampers are the brand name you know. Fluidampr is related to the parent company, Vibratech Torsional Vibration Dampers - TVD is where the science happens. Automotive performance powertrain engineers, production engine builders, and aftermarket performance kit manufacturers have an experienced partner through Fluidampr to develop and integrate turn-key torsional dampers with exceptional quality.

Why your engine needs a crankshaft damper:

Each time the air/fuel mixture inside a cylinder is ignited, the combustion that occurs creates a torque spike that is applied to the crankshaft through the piston and rod. This torque spike is so severe that it turns the crankshaft, twists the crankshaft ahead of its regular rotation, and then rebounds. This twisting action is known as torsional vibration. When these torque spikes and forces get into phase with the natural frequency, critical torsional harmonic vibrations occur and can be severely destructive to the bearings and the crankshaft. Your engine Powerstroke creates torsional vibrations, which create a parasitic loss that also robs an engine of valuable brake horsepower. Viscous Harmonic Dampers are designed to control those harmful waves. The difference between the OEM damper and a high-performance Fluidamper viscous harmonic damper is clearly seen on a dynamometer. 

A new Fluidampr crankshaft damper on your engine will not only protect your engine from destructive torsional vibrations but will also increase your engine's power output levels. Dynamometer testing has proven increases in both the TORQUE and HORSEPOWER levels on every single engine using an American-Made Viscous Damper. Today's High-performance stock engines or modified engines running chips and programmers are exceptionally vulnerable to torsional vibrations. A Fluidampr viscous damper controls torsional vibrations far better than the stock damper.

Save your crankshaft and more by installing a new Fluidampr Viscous damper today. Fluidampr® vibration dampers have been tested on both stock and high-performance tuned diesel trucks. Dynamometer tests have proven consistent increases in horsepower and torque in the Chevrolet, Dodge, Ford, General Motors, Toyota, Honda, Subaru, Lexus, Toyota, Acura, and Mitsubishi applications.

What is the difference between a harmonic balancer and a crankshaft damper?

A harmonic balancer is sometimes called a crankshaft damper, torsional damper, or vibration damper. These terms refer to the same thing as a harmonic damper, except that the balancer includes a counterweight to control the destructive torsional vibrations produced by the engine's power stroke.

Fluidampr viscous crankshaft vibration dampers are available for the following engine categories:
