      Fluidampr Performance Diesel 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 to the 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 power 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 also lead to increased wear rates on your rotating assembly such as crankshaft and bearing damage.

      Fluidamper produces High Performance Diesel Dampers for the following diesel engines:

      • Cummins Diesel in the Dodge Ram trucks
      • Powerstroke Diesel in the Ford Super Duty trucks
      • Duramax Diesel in the Chevy and GMC trucks
      • GM 6.5L Diesel in the Chevy and GM trucks
      • GM 6.2L Diesel in the Chevy and GM trucks

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

      The 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 rise torsional vibrations above a level the OEM damper was not designed to handle. A stock harmonic balancer is 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.

      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.

      Warning signs that the stock harmonic vibration damper has failed:

      • 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.
      • The Damper's outer ring is now separating from the hub.

      Due to the 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.

      What exactly does a Harmonic Balancer Do?

      The harmonic balancer's job is to control the destructive crankshaft torsional vibration is produced with each power stroke of the engine during the combustion process. The power cycle of the engine generates a twist and rebound effect upon the engine's crankshaft, which causes these torsional or harmonic vibrations to occur. Torsional vibrations are the end-to-end twisting or rebound motion exerted on the crankshaft during each power stroke. A torsional harmonic balancer is designed to control these forces. 

      Fluidampr High Performance Diesel Crankshaft Damper Features and Benefits:

      • Designed to accommodate stock to extreme power levels.
      • It Will not wear out and will last the full life of your engine.

      • Protect your truck with the technology high power diesel OEMs use.
      • Only a Fluidampr performance diesel damper provides premium, broad range control of destructive crankshaft torsional vibration for optimum performance and durability.
      • The installation of a Fluidampr viscous harmonic damper reduces wear on critical internal engine components.
      • The Fluidamper viscous crankshaft damper provides the protection you need when engine modifications are done to increase horsepower or when rotating assembly parts are upgraded.
      • Features high quality, long-lasting viscous silicone with precision CNC machined and computer balanced high-grade steel components.
      • Installation of a CNC balanced Fluidampr never requires additional tuning or maintenance required.

      Fluidampr customers have completed thousands of Dynomometer tests which depict the horsepower and rear-wheel torque gains obtained on a stock or tuned diesel engine by only changing the stock elastomer to a Fluidampr Performance Viscous Type Damper.
