Harmonic Balancer
Looking for recommendations on replacing the stock 1972 455HO harmonic vibration damper on my car. Is there an excellent quality replacement with the correct 4 bolt pattern so I can use the original pulleys?
Thanks for any input. Last edited by 4birds; 02-27-2021 at 11:51 AM. |

Powerbond makes an excellent street damper that also has degree markings #PB1056ST. I believe the same unit is sold by Pioneer in their packaging.
It also has the correct bevelled edge required for some A/C pulleys (which the SFI rated model does not). https://www.rockauto.com/en/parts/da...+balancer,5512

Street use and occasional 1/4 mile "testing ". Max RPM 5500. Not a race car.

If you go on a track you need an SFI balancer to pass tech, so my NOS one is out.

The sponsor of this web site Ames performance carries a replacement one that’s SFIb rated one for $150, and it takes the 4 bolt pulleys.
They have the bolt and thick washer also and I would highly recommend replacing the bolt!

SFI isn't required until 10.99 or quicker.

Pioneer offers an SFI version. Have one on my own engine and have used a lot of them over the years with zero issues. We even used one on the last 505 we did here making almost 750hp and it has lived fine for quite a few years now.....
