Harmonic Balancer

[alexfloresaz]

Hi, sorry to jump in. I read this post a few months ago. I did buy the newcomer racing ATI Damper. over $900 shipped. I installed it, and did not like it. Slightly higher vibration at 5,500 rpm area vs stock damper. My rotating assembly was balanced before assembly. It feels like if it was not tuned for a straight 6 engine. As mentioned here before it is probably for a V8.
