That damper piece people think dampens vibration is a rubber gasket...that's it. It's made out of iron and heavy, not to magically remove non-existent super dangerous vibrations that emanate from our engine. It's the same reason they made the fluwheel a dual mass, to smooth things out, but it also saps engine response (and power). There aren't a lot of newer vehicles or engine designs that require an external damping mechanism. It's just a pulley. Even the stock piece is called a crank pulley. But alas, I'm wasting my breath to half the forum
