Harmonic Balancer

 

What is a harmonic balancer?

The harmonic balancer (also called crankshaft damper) is a round metal and rubber disc that works as a damper to absorb vibration caused torsional crankshaft harmonics and resonance from the engine as each cylinder fires.

 

Are aftermarket harmonic balancers worth it?

Yes. OEM harmonic balancers are designed specifically for the level of vibration caused by a stock, factory engine. As you add horsepower, the harmonics and resonance change, and the OEM harmonic balancer simply cannot provide the same level of damping. Increasing horsepower without adding an upgraded harmonic balancer will cause premature wear and failure of the damper, as well as putting more wear on your engine.
