7.3L Powerstroke Fluidampr Harmonic Damper

If you're serious about building a reliable, high-performance 7.3 Powerstroke, don’t overlook the heart of engine longevity — crankshaft vibration control. The KDD-spec Fluidampr for the 7.3 is the ultimate solution for eliminating harmful harmonics that can destroy your engine from the inside out.

Unlike factory dampers that only target a narrow frequency range (and wear out over time), Fluidampr’s design controls all crankshaft vibrations across the entire RPM band. Inside the laser-welded steel housing, a precision-machined inertia ring is suspended in a proprietary silicone fluid, dynamically absorbing and dissipating vibration in real time. The result? A smoother-running engine, reduced main bearing and timing gear wear, more stable valvetrain operation, and greatly reduced risk of crankshaft failure — especially critical when pushing power beyond stock limits.

SFI-approved for competition, this is not just a performance upgrade — it’s essential protection for your investment. Whether you’re daily driving, towing heavy, or running elevated RPM in competition, the Fluidampr delivers the confidence to push harder and go further without sacrificing reliability.

Key Benefits:

• Controls all crankshaft harmonics, not just a narrow band

• Reduces main bearing and timing gear wear

• Improves valvetrain stability and performance

• Protects against crankshaft failure in high-power builds

• SFI-approved for competition use

• Maintenance-free, built to last the life of your engine

Don’t leave your bottom end exposed — step up to the Fluidampr and protect your 7.3 Powerstroke from the destructive forces you can’t see.
