ATI Performance Products 918856 Harmonic Damper
These Supercharged series dampers place the powerful protection of ATI Super Damper inside of the crankshaft blower pulley. Available in 66 to 8mm pitch, and 40 to 14mm pitch, these balancers eliminate torsional crankshaft vibrations and feature dual-keyway hubs. These balancers exceed SFI 18.1 specs, have laser-engraved 360 degree timing marks, and are finished in a black zinc chromate. Numerous pulley offsets are available to keep the blower drive as close to the engine as possible, reducing the bending moment to the crankshaft nose.
