Topic has been beaten to death in regard to actual dampening. N/A gets a pass, but anyone that cares about their TT should stick to OEM or OE-style aftermarket. The more expensive upgrades are also available e.g. Fluidampr, ATI, etc.
I agree with Alan. I’ve observed bearing wear on personal cars I’ve bought with aluminum crank pulleys. It’s pretty evident because the copper wear from flywheel side to crank pulley side increases quite a bit.
Just get a stock replacement like Dorman for $70. If you’re wanting 600+AWHP, then spring for the Fluidampr.
It doesn't really have a lot to do with bearing wear, it's about the twisting of the crank at one end with respect to the other It will oscillate at it's resonant frequency and eventually fail.
The rubber of the damper soaks up the energy and damps any oscillations. The main bearings will wear anyway but that's really to to with the imbalance in the middle of it.
