Harmonic damper

[R.O.R-2.0]

my aaz flywheel weighed 12.8lbs stock. IIRC around 9lbs and under it is getting really bad.

12-13 is stock.. they do make heavy flywheels tho, that are 19#, and have a much thicker ring in front of the ring gear..

I only started to notice this when I went from the 190 diesel clutch to the 210 gasser

. . . That's where I'd start lookng

i would think that your clutch/pressure plate/flywheel is the issue..

too light of a flywheel will give these things some pretty funky harmonics as well. didnt you install a 6#, or 9# wheel?
