Description
Harmonic imbalance causes accelerated crankshaft wear and vibration-induced failures—especially critical in high-RPM and forced-induction Small Block Ford applications. The ATI SBF 6.325 Super Damper isolates destructive harmonic frequencies before they damage your engine, protecting your investment while maintaining precise crankshaft geometry. SFI 18.1 certification ensures this damper meets sanctioning body requirements for competition and street performance alike.
