Fluidampr 800241 Ford 6.7L Power Stroke Steel Externally Balanced Harmonic Damper

The Fluidampr 800241 is a precision-engineered, steel externally balanced viscous harmonic damper designed for the Ford 6.7L Power Stroke diesel engine. Built to replace the factory elastomeric balancer, this performance crankshaft damper delivers broad-spectrum torsional vibration control across all RPM ranges and power levels — making it an ideal upgrade for both stock and modified Power Stroke engines.

Unlike rubber-based OEM dampers that degrade over time and protect only a narrow vibration frequency range, the Fluidampr viscous design continuously self-tunes in real time. A free-rotating inertia ring sits inside a laser-sealed outer housing, separated by a shear gap filled with high-viscosity silicone fluid. As torsional vibrations shock the inertia ring, the silicone shear force converts that energy into heat, which rapidly dissipates through the housing — neutralizing destructive crankshaft harmonics before they can cause damage.

Key Features:

• Viscous silicone fluid design provides real-time, self-tuning torsional vibration control
• Steel construction with black zinc finish for durability and corrosion resistance
• Externally balanced to match Ford 6.7L Power Stroke specifications
• Precision CNC-machined and computer-balanced components exceed OEM tolerances
• SFI 18.1 approved for racing and high-performance applications
• Automatically adapts to engine modifications — no re-tuning required
• Maintenance-free: never needs to be rebuilt or re-tuned
• Reduces wear on main bearings, timing gear, oil pump, and crankshaft
• Improves valvetrain stability and engine timing accuracy
• Made 100% in the U.S.A. | ISO Certified

The Fluidampr 800241 is the preferred choice for Power Stroke owners running tunes, upgraded injectors, performance intakes, exhaust modifications, or any other power-adding upgrades. By controlling destructive harmonics at the source, this damper helps protect your engine investment and supports long-term performance and durability.
