Fluidampr Performance Steel Internally Balanced Damper for Select 1986-2005 Mazda 323, Miata, MX-3, and Protege

Fits select 1986-2005 Mazda 323, Miata, MX-3, and Protege models.

Protect your engine's bottom end with the Fluidampr Performance Damper (MPN: 521001). Unlike factory harmonic balancers that use a rubber ring to dampen specific frequencies, this viscous damper features a precision-machined steel housing and an internal inertia ring floating in a thin layer of silicone. This design provides continuous, self-tuning protection across the entire RPM range, which is critical as engine modifications change the frequency of torsional vibrations.

Engineered for longevity and performance, this unit is CNC machined from high-grade steel and finished with a corrosion-resistant black zinc coating. It features engraved timing marks for accurate tuning and is SFI 18.1 certified for racing applications. This damper is internally balanced and requires no maintenance or tuning, making it a direct-fit upgrade for high-performance builds.

• Vibration Control: Superior viscous design manages torsional vibration at all engine speeds.

• Construction: CNC machined high-grade steel with engraved timing marks.
• Finish: Corrosion-resistant black zinc.
• Certification: SFI 18.1 spec for track and street use.
