Just to see how many places use Your technically correct term of 'damper' I dialed up Rock Auto and Autozone and O'Reilly and none of those places recognized the term 'harmonic damper' in their search field. Summit Racing lists them both ways but Harmonic Balancer came up with the most items so I guess the world can recognize the term balancer without being penalized with the technical omission of the noun damper. Just screwing with You so don't get annoyed.
