Description Applications
Additional power and RPM from upgrades increases the naturally occurring characteristics of harmful crankshaft torsional vibrations. By installing a Fluidampr viscous damper (crank pulley) you will reduce wear on the main bearings and timing gear, achieve more accurate valvetrain operation and lower the risk of crank failure.

Unlike rubber based dampers, Fluidampr automatically adapts to your modifications, then continuously self-tunes in real time to optimum damping at both peak levels and across a broad changing frequency range. As the engine revs up, torsional vibration suspends the inertia ring and reduces its weight felt on the crankshaft. Measured as rotating weight, this effect helps maintain quick revs while preserving optimum dampening.

  • Good for instant protection against turbo and NOS power surges.
  • Precision machined and computer balanced components.
  • Never needs to be tuned or rebuilt.
  • SFI Approved.
  • Made 100% in the U.S.A.
  • ISO Certified.
