I'm curious if there are any benefits from replacing the stock harmonic damper with an aftermarket one. My engine (2001 RT/10) seems fine, damper bolt is still tight from the factory, no odd vibrations in the car. The engine is still OEM...no mods.

Is there a way to test the stock damper to ensure it is still good?

ATI and Powerforce+Plus look to be the two that are readily available. ATI is close to double the price of the P+P damper, but hard to tell if it is worth the price differential. Thanks.
