Description

ATI designed this 917220 Super Damper Harmonic Balancer for Small Block Chevy engines. Super Dampers are the only harmonic balancers developed just for high performance engines, tested in Winston Cup competition as well as drag racing engines for over ten years!

The inner as well as outer shells contain the steel inertia weight that has eight computer machined grooves to retain the proper durometer O-rings. This balancer comes in a black zinc chromate finish with computer controlled, laser engraved 360 degree timing marks.
