Are Dorman or Pioneer balancers any good? Dorman 594-243 or Pioneer DA-2250 I can get the dorman with a lifetime warranty and the pioneer with a 1yr warranty and 20% discount though my job for either. [/i] |

I'm not buyin'. Gimme known-good Australian-made quality over Chinese R&D ("Receive & Duplicate") any ol' day -- discount or no discount. |

http://www.ebay.com/itm/380455093128 for a new Australian-made single-groove damper that accepts the same bolt-on steel add-on pulleys for A/C (rear) and/or power steer (front). http://www.ebay.com/itm/360151441646 for a new factory 3-groove truck damper. VERY heavy. I have one on my '73 Dart. |

What would the advantage to the truck dampener be? More mass = more dampening effect? |

Three pulleys without bolt-on sheaves. I don't know about more damping effect -- it's difficult to imagine more being necessary or beneficial. |

Ah. So the only advantage to the truck dampener is a guaranteed three pulleys without the need for bolt on pulleys? I agree about no more damping being necessary. I suppose the added mass could offer a minimal MPG increase by acting as a mini flywheel if the engine was operated at high RPM for extended periods of time. But I doubt it would be noticeable. |

I am guessing (but it's just a guess) that what's heavy-duty about this 3-groove damper is the 3 integral sheaves. It's a heavier-duty belt drive, not a heavier-duty crank vibration damper. |

Yup. It's doing just fine on the forged crank in my '73. |

Why not reuse the original one? I have never had one fail, even on hipo motors. I think the pre-64 ones might have been more prone to failure. Lou |
