Crankshaft Balance Ring?

Although often referred to as the harmonic balancer, because our Cummins is internally balanced (the crankshaft itself being balanced), the damper on our engines does not balance the engine. It damps harmonic vibrations and, as such, is a harmonic damper.

I doubt they balance them to blueprint specs anyways so there could be some, not much, benefit to a balance ring. It'd be more noticeable at high revs.
