Luk DMF075 Clutch Flywheel

LuK DMF075 Dual Mass Flywheel Overview

The LuK DMF075 is a dual mass flywheel engineered for Ram 2500 and Ram 3500 diesel truck applications. Built to match the original LuK design, it helps control drivetrain vibration and supports smoother clutch engagement in demanding towing and hauling use.

For Ram 2500 and Ram 3500 owners searching for a replacement clutch flywheel, the DMF075 is a direct-fit OE-style solution with application-specific tuning and precise tooth count for proper starter engagement.

Key Features

• Dual mass flywheel design for vibration isolation and driveline refinement
• Flywheel diameter: 12.598 in. / 32 mm
• Flywheel cup depth/step height: -0.606 in. / -15.4 mm
• Flywheel inner diameter: 20.3 in. / 7.992 mm
• Number of teeth: 152
• OE-style replacement for Ram 2500 and Ram 3500 clutch service
• Part number: DMF075

Detailed Description

LuK designs the DMF075 as a dual mass flywheel tuned for the specific demands of the vehicle application rather than a universal solid flywheel replacement. The dual mass construction helps reduce the transfer of engine torsional vibration into the transmission, which is important in heavy-duty Ram 2500 and Ram 3500 trucks. Using the correct flywheel geometry, step height, and tooth count helps maintain proper clutch operation and starter ring engagement. This part cross-references Sachs DMF91156 for the same application.

Compatible With 2005-2010 Dodge Ram 2500, N/A; 2005-2010 Dodge Ram 3500, N/A; 2011-2018 Ram 2500, N/A; and 2011-2018 Ram 3500, N/A. The DMF075 part number is also commonly searched alongside Ram 2500 flywheel replacement and Ram 3500 clutch flywheel service.

What It Helps Address

• Excess drivetrain vibration felt through the clutch and transmission
• Premature wear associated with incorrect solid flywheel conversions
• Harsh clutch take-up during starts and shifts
• Starter engagement issues related to incorrect tooth count or dimensions
• Stress transferred to engine mounts, gearbox components, and crankshaft interfaces

Installation Notes and Tips

Verify flywheel diameter, step height, inner diameter, and tooth count before installation. Match the DMF075 to the exact Ram 2500 or Ram 3500 model year and drivetrain configuration listed in the fitment data. Inspect the clutch system, starter, and related hardware for wear before reassembly, and follow the vehicle manufacturer’s service procedures and torque specifications.

Quality Assurance

LuK supplies OE-level clutch and drivetrain components, and this dual mass flywheel is built to the same application-specific standards expected from the original equipment design. The DMF075 is intended to preserve the driveline characteristics required for Ram 2500 and Ram 3500 service use.
