Dual mass flywheel do your self a favor and contact South Bend clutch and see what they offer to rid yourself of it. Maybe a nice dual disk clutch, way less than $4K even with a shop install.

The Ram “dual mass system is the “weak link” of the Ram manual transmission driveline. Go with Southbend or Valair clutch/pressure plate/ flywheel systems.....ultimately, you will be very happy you did. However, you will pick up a lot of transmission noise (aluminum transmission housing harmonics in conjunction with the Diesel engine). Many people suggest going to Mobil Delvac I 75W-90 as the transmission lube replacement....rather than ATF. The Mercedes transmission ( if it’s the same as ours) is the same transmission used in Europe on “big” trucks. They use the European equivalent to the oil I suggested. This lube offers better protection for the tyranny, helps tame the noise (harmonics) some, but makes shifting a bit stiffer when cold! Also recommended by many, when the tranny is refilled after clutch change-out, as it will be filled from the top thru the shift tower, add an additional quart of lube. This will also help with the transmission harmonics! memtb
Under no circumstances use anything other than the recommended transmission fluid in an NV5600 transmission. And that means no ATF, no Delvac 75W-90. And I don't believe the NV5600 has an aluminum transmission housing. Although that might be why it weighs a million pounds. :)
As far as them wanting $4000, that's way out of line. I had a Valair Dual Disc clutch with new flywheel installed on my 2001 Cummins dually 2 1/2 years ago and it cost me about $1000 for the clutch/flywheel and about $600 to have it installed. FWIW the clutch is the known weak point with the OEM NV5600 transmission. I got 97,000 miles out of mine before it started to slip. If you tow heavy a lot, it's not a matter of "if", only a matter of "when".
And yes, a dealer will probably want almost double that amount, plus they will want to go back with OEM parts and you'll be looking at another visit if you keep the truck long enough. IMO skip the dealer.
