ATI Super Damper Supercharged Series Harmonic Balancers
These Supercharged series dampers place the powerful protection of ATI Super Damper inside of the crankshaft blower pulley. Available in 66 to 77-tooth 8mm pitch, and 40 to 51-tooth 14mm pitch, these balancers eliminate torsional crankshaft vibrations. 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.
