I had huge issues with the South Bend in my 07 3500 with the G56 trans. I even went to their shop in South Bend and they told me it sounded normal, even after taking them for a drive. I eventually changed it out for another aftermarket clutch as I sure wouldn't go back to the dual-mass flywheel.

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
