A dual mass flywheel has to pieces of steel. One mounts to the crank, the other the clutch bolt to. I'm not sure what dodge uses to connect the two halves, but ford used to use springs. I've seen quite a few fords that have had their flywheels blow apartsoI don't like them.

 

i had 88ooo km's on my truck when i had to replace the clutch

 

jake. . .it uses the same method. . .a huge spring wrapped around the outside of the flywheels. . .

all it does is dampen the inherent shakieness of the engine for a smoother ride and smoother shift engagement and ease the stress on the syncro's.

 

Definatly worth getting rid of then. Just replaced the clutch in my buddies ford, his dual mass was about ready to go. He caught it just in time.
