ATI SBF 6.325 Harmonic Damper - SFI 3-Bolt 917511AK

Harmonic dampers are critical to engine longevity—they absorb crankshaft vibrations that, left unchecked, lead to premature bearing wear and catastrophic failure. The ATI SBF Super Damper delivers proven durability with a precision-engineered elastomer core that isolates destructive harmonics while maintaining accurate ignition timing. For Ford Small Block engines running hard, whether on the track or the street, this is the standard that racers and serious builders trust.
