Wanted to mention, I sent out my balancer to the Damper Doctor, and just got it back. It looks pretty good. It took about a month, because I wanted my original one back. Cost was $59.95 + $10 shipping. They pressed on a seal sleeve for free. ------------------

Wow! Here's the opening line of spiel from Damper Doc's website ...
"The harmonic balancers are cleaned thermal hi temperature furnace which does a stress relief type of cleaning this lets the molecules relax back to their natural state. They are then "steel shot" blasted, again a cleaning and stress relieving operation."
I'd love an explanation of how this works. Does this mean the molecules get shifted from their original alignment (i.e., when they were first cast) through years of stressful use, and can be returned to the original alignment just by heating or blasting? The heating part I can understand -- maybe. The blasting I don't get.

Heating stress relieves materials, that process is used all the time. Shot peening compacts the surface, that's a common practice, too, especially for connecting rods, for example.------------------

Wow Steve you dug up an oldie! I got a rare 440 Mopar damper from "The Doc" and everything looked and worked great. It was for my son's '70 440 Dart. I would definately recomend them for anyone that doesn't need an SFI approved damper. SteveW
