Superior Harmonic Balancer Dampers for Your Street or Race Vehicle
ATI's patented Super Damper is the only harmonic balancer developed exclusively for high-RPM performance engines (6000+ RPM). They feature a proven 2-in-1 elastomer design that bolts directly to the crank hub. ATI dampers are tested in Nascar competition settings and for over two million cycles in drag racing engines. Available in aluminum or steel shell material with a black zinc-chromate finish and with computer-controlled, laser-engraved 360-degree timing marks.
