The Fluidampr harmonic Damper is engineered for Ford 302/351 engines with an internal balance, providing a direct replacement for 28oz external balance setups in custom builds. It also fits 300ci I6 engines if 0.250" is machined from the end of the hub. Designed to reduce crankshaft vibrations, this Damper improves engine smoothness, longevity, and reliability for performance or street applications. Its precise construction ensures optimal engine timing and power delivery in high-performance or custom Ford projects.
Constructed from durable steel with a corrosion-resistant black zinc finish, the Fluidampr Damper is built to last. Engraved 2-degree increment timing marks from 50 BTDC to 10 ATDC allow accurate tuning and setup. The 4-bolt standard Ford pulley pattern ensures compatibility with most stock setups, though some applications may require a pulley spacer (#717656) or custom pulley for certain model years. Certified SFI 18.1, this damper meets rigorous safety standards for street and racing performance.
