I just put a dual disk on my g56 2007.5 Cummins. I don’t really mind the rattle in neutral but in the lower rpm band I can’t even use 5th or 6th it’s so noisy and loud and in the rest of the gears it sounds like I’m lugging the engine under 1500rpm. Has your shop had any experience using a FLUIDAMPR crank pulley and if so has it helped? I read that some people with the g56 it helps a lot and others it was a giant waste of money. Also any particular gear oil that may help the noise?
Can’t wait to get mine

You sure the the disks are in there in the right order and facing the right way? Sounds like something ain't right.
