Magnum balance....

If the factory Ram flexplate didn't have weights on it, you don't need 'em on it now; it's an (almost certainly) internally balanced 5.2! You say you're running the stock style one piece balancer (Which I assume you to mean vibration dampener)...which one? Magnum or 340?

If you think your Ram mill is a 5.9, you need to make sure before you go hanging (or removing) weights on it. The 5.9 had weights (on the flexplate), and they were different than the 360 weights! This goes for dampeners, too.

Magnum mills didn't have weights on the converter that I've ever seen and I'm wagering you have a 5.2 and just need an unweighted converter, flexplate, and internal dampener.

Side note, I'm confused and this info may be totally worth what you paid for it.
