DMF058 Dual Mass Flywheel: Dodge Ram 2500 3500 4500 5500 5.9L 6.7L Diesel with G56 trans and 12.5 in. clutch

This is NEW OE Dual Mass Flywheel. All Dual Mass Flywheels are manufactured by OE manufacturers. The picture (when available) is of the actual product, and shows both sides. If the flywheel you are replacing is different in any way, please contact us for technical assistance.

A dual mass flywheel (DMF) absorbs vibrations from the engine through the transmission input shaft and on through the rest of the drivetrain. The DMF minimizes Gear Roll-over noise generated in manual transmissions that are mostly filled with automatic transmission fluid these days. The reason it is called a dual mass flywheel is that there are two plates joined by a bearing and dampner spring assembly that often includes a friction pack as well. The first plate mounts to the crankshaft and has the starter ring gear on it. The second plate is where the pressure plate bolts to.

This type of flywheel is not recommended with performance clutches due to it's designed torque limitation. In addition, when used in towing applications, the weight of the towed load can adversely affect the life expectancy of this type of flywheel. As such we do not warrant this flywheel when used in either heavy towing or performance applications..

These flywheels cannot be resurfaced because the resulting grinding grit will damage the internal components.

This is a direct factory replacement part and no modifications are necessary to make it fit.

Important Note:
The OE setup has an adapter plate between the crank & flywheel. If this is missing, order the following parts from a Dodge dealer: 1 of 52104720AE (adapter plate), 1 of 04798968 (backing plate), 8 of 06508033AA adapter plate to flywheel mounting bolts, and 8 of 05085962AA adapter plate to to crankshaft bolts. 

Bolt 06508033AA is M10 x 1.5 x 25.0.
Bolt 05085962AA is M12 X 1 x 34.0.
