Quality Harmonic Balancer Options
The Pro Race external balance damper comes with a weight for the pre-magnum 360, it weights .92 lbs. One can also buy a weight for magnum 360's, it will bolt to that balancer, and weights .56 lbs. You can also run that balancer with no weights, for neutral. For whatever reason the Pro Sport version for external balance also uses a weight of .92 lbs for the pre-magnum 360, or you can run it with no weight for neutral balance. Probably will call them to find out why they don't offer a .56 weight for magnums......
