I have a 2006 ram 3500 4 door 4x4, 5.9 6 spd. The truck at about 96,000 miles began to have a very rough idel. I ran a treatment of power service additive though it and it helped. At 130,000 same thing, so I took it to a local shop that mainly works on cummins. He informed me that the stock dual mass flywheel was comeing apart and needed to be replaced. So after some looking and learning I went with a up grade solid flywheel & clutch kit from south bend clutch. Now Iam looking for any one who has some instructions or maybe just some helpfull hints to send my way would be great. Thanks : Chuck Bonham.
