Last winter while doing a refresh on my 410 stoker build,my builder magnafluxed my forged Eagle crank.This is the crack he found.I was lucky to have caught this before catastrophic failure.I replaced the crank with a forged Molnar crank.You can really tell the difference in quality by just comparing.Oh I,ve also been running an ATI Super dampner for 12 year without issue.Molnar crank on right

I can say without any reservations that your damper is NOT functioning like it did when it was brand new. It can’t be. The rubber has lost a bunch of durometer and several of the bands are probably fractured.

One of the better things about the ATI damper over other elastomer dampers is it can (and should) be rebuilt. Rubber is not a lifetime materiel.

Not sending it in for a tune up is pressing your luck.
