About the Brand - Fluidampr

Fluidampr logo styled in black on a white backgroundFluidampr® — Viscous Harmonic Balancers for Serious Performance

Fluidampr harmonic balancers (viscous torsional dampers) are engineered to control harmful crankshaft vibration across the entire RPM range. By converting twisting vibration into heat inside a sealed silicone-filled housing, Fluidampr helps stabilize the rotating assembly—improving durability, throttle response, and long-term reliability on street, track, and boosted builds.

Key Benefits

  • Reduces destructive torsional vibration to protect bearings, timing components, and the crankshaft.
  • Broadband damping performance—effective from idle to redline (no re-tuning or external weights).
  • Smoother operation for cleaner data, more consistent power delivery, and better drivability.
  • Maintenance-free sealed design built for high heat and high RPM environments.
  • Many applications offer SFI 18.1 certified options for competition use.
  • Precision construction with CNC-machined housings and wear-resistant internal components.

Ideal For

  • Turbocharged, supercharged, or high-compression engines.
  • Endurance racing, road course, time attack, drag, and spirited street performance.
  • Engines with lightweight flywheels, solid mounts, or other mods that amplify vibration.

What makes Fluidampr different?

Unlike tuned elastomer or pendulum balancers designed for a narrow frequency range, Fluidampr uses a viscous shear design that continuously adapts to changing harmonics. The result is reliable, broadband damping as you modify the engine or change operating conditions—no retune required.

Smoother drive, big NVH reduction

After install, shifter vibration dropped significantly and the car felt much smoother; fitment was easy.

V
Verified Buyer
Noticeably smoother, less vibration

Immediate improvement in smoothness and reduced vibration; install was straightforward.

V
Verified Buyer
Install notes: crank bolt & spacer; works great

Required removing the crank bolt; on a 1.6 long‑nose without a timing wheel, a spacer was needed to keep the belt aligned. Once installed, performance was great.
