Crankshaft Vibration Dampers by Vibratech and Fluidampr

Our High Quality American Made Dampers for your vehicle include:


Heavy Duty Diesel Engine Harmonic Dampers

The crankshaft damper is a vital component of your heavy duty diesel engine. This harmonic balancer is one of the most important pieces of equipment on your engine. Vibratech TVD is an American Company that has been producing American Made Torsional Viscous Vibration Dampers for over 65 years. These Vibratech TVD viscous torsional dampers are a free rotation inertia ring surrounded by a viscous silicone fluid enclosed in a precision machined steel housing that is laser welded. The entire liquid-filled crank damper assembly is computer balanced to ensure optimum performance of your heavy duty diesel engine. These performance diesel dampers work on both stock and highly modified diesel engines. Original equipment dampers that utilize rubber or elastomer rings to dampen vibrations are prone to deterioration that may destroy engine components in as little as 1 to 3 years. Rubber damper rings dry out and crack over time, reducing the effectiveness of the damper. Exposure to oils and solvents can cause rubber damper rings to swell and quickly break down. These changes in hardness and elasticity, over time, will cause damper failure and damage to expensive engine components.

Performance Diesel Viscous Dampers

Fluidampr produces the High Performance Viscous Diesel Damper trusted by Diesel truck owners everywhere!Fluidampr Diesel Dampers are ideal for anyone looking for a replacement damper or for an individual looking for a superior harmonic balancer for a diesel engine with increased power. From stock power to a full-blown competition motor Fluidampr harmonic crankshaft balancers have you covered. A regular stock damper is considered a wear item, and it requires both inspection and replacement. A diesel engine with performance upgrades drastically increases the harmful torsional vibrations produced with every single powerful stroke of your internal combustion engine. These torsional vibrations or harmonics must be controlled as they are a primary source of horsepower and torque loss on your engine. The vibrations can also lead to increased wear rates on your rotating assembly such as crankshaft and bearing damage.

Sport Compact Viscous Harmonic Dampers

Fluidampr Sport Compact crankshaft dampers are ideal for anyone looking for a replacement damper or the individual looking for a superior harmonic balancer for a modified sports compact engine with increased power and higher engine RPM levels. From stock power to a full-blown competition motor Fluidampr harmonic crankshaft balancers have you covered. A normal stock damper is considered a wear item that needs to be replaced. The OEM dampers were also designed to operate at the stock power level. This is often suggested by the OEM in your service manual and in as little as 30,000 miles. The change interval is a model-specific requirement. Sports compact performance upgrades drastically increase the harmful torsional vibrations produced with every single power stroke of an internal combustion engine. Any engine power upgrade can cause an increase in vibrations. Increased vibration levels generate an additional workload on the stock rubber damper which causes the OEM rubber damper to overheat and fail prematurely. Stock dampers are tuned for maximum effectiveness with a stock rotating assembly when it's spinning at low rpm's. When the pistons, connecting rods, or crankshaft are changed or modified, or normal rpm range is increased, the effectiveness of a stock damper is reduced.

Domestic Viscous Harmonic Dampers

Only a viscous damper from Fluidampr is designed to provide effective control of all engine harmonic vibrations, regardless of the rpm at which they occur and regardless of the crankshaft's natural frequency. The Fluidampr Viscous Sport Compact Dampers provides the maximum level of protection for the crankshaft, main bearings, valve train components along with increased power output. All Fluidampr Sport Compact Dampers are designed as a maintenance-free bolt-on performance upgrade. Fluidampr is effective on both race and street applications. 

Fluidampr harmonic crankshaft dampers are the only viscous dampers that are race-proven and built in the USA. These high performance replacement dampers are very different than your stock elastomer harmonic balancer. Fluidampr domestic performance dampers protect across a broad frequency range and can become more effective as your power level increases. These dampers are designed as application-specific replacement crankshaft dampers. 

The destructive effects of torsional vibrations cause:

  • Crankshaft Cracking or Failure
  • Excessive Bearing Wear
  • Extreme Gear Wear or Failure
  • Broken Accessory Drives
  • Thrown or Slapping of Belts
  • Increased driver fatigue

Signs that the OEM stock vibration damper is now failing:

  • The bonded rubber on the harmonic balancer is cracked.
  • There is bulging or missing rubber between the hub and outer ring.
  • Age and repeated heat cycles have caused the rubber to degrade
  • A collective failure will be the outer ring separating from the hub causing damage inside the engine bay.
  • There is a noticeable increase in the level of in-cab vibrations.
  • A wobble of the damper is apparent during engine operation.
  • Damper's outer ring is now separating from the hub.

Due to countless combinations of performance upgrades, the simplest and most cost-effective solution for controlling destructive torsional vibrations is to install a Fluidampr performance diesel damper. By design, the Fluidampr viscous vibration dampers protect your engine from these torsional vibrations across a broad range of frequencies and power levels. The earlier a Fluidamper performance damper installation takes place, the more you’ll benefit from its protection, performance, and the ability to ensure long term engine life.

Why Do I Need A Performance Harmonic Balancer / Crankshaft Damper?

Installation of any performance parts that increase the engine's power output or torque, such as intake, rods, pistons, flywheel, flexplate, fuel pump, injectors, exhaust, cams, and any ECM changes typically will increase in torsional vibration magnitude and frequency. These performance upgrades also raised torsional vibrations above the level the OEM damper was not designed to handle. Stock harmonic balancers are typically tuned for a 50hz peak variance at a particular power level. Alter any of the engine's rotating assembly parameters, and it may leave your critical engine components unprotected when torsional vibration is at its peak.

High Performance Diesel Crankshaft Damper Features and Benefits:
