• Flywheel cup depth/step height: -0.768 in. (-19.5 mm)
• 130-tooth ring gear
• Direct-fit replacement for BMW M5, BMW M6, and BMW M6 Gran Coupe applications
• Part number: DMF184

Detailed Description

LuK DMF184 is a clutch flywheel engineered as a dual mass flywheel for BMW high-performance drivetrains. The measured flywheel diameter, inner diameter, step height, and 130-tooth count support accurate alignment with the original transmission and clutch system. LuK builds this DMF to match the specific vehicle application rather than using a one-size-fits-all solid flywheel approach. This matters on BMW M5, BMW M6, and BMW M6 Gran Coupe models where drivetrain smoothness, component protection, and consistent engagement are critical. Part number DMF184 is also referenced by 4150805100 and 21212284514 for the same application.

Fitment

• Fits 2014-2019 BMW M6 Gran Coupe, N/A
• Fits 2013-2018 BMW M6, N/A
• Fits 2013-2016 BMW M5, N/A

What It Helps Address

• Excess drivetrain vibration during acceleration and shifting
• Premature wear on engine mounts from torsional movement
• Gearbox stress caused by improper flywheel damping
• Crankshaft damage associated with incorrect flywheel selection
• Clutch engagement inconsistency on high-output BMW applications

Installation Notes

Verify flywheel diameter, tooth count, and step height before installation. Inspect the clutch, release components, and related drivetrain parts for wear while the transmission is removed. Proper torque procedures and clean mating surfaces are important for correct operation on BMW M5, BMW M6, and BMW M6 Gran Coupe models. Confirm the replacement part number DMF184 matches the vehicle application before assembly.

Quality Assurance

LuK supplies OE-level drivetrain components and tunes this dual mass flywheel for the specific vehicle platform. The DMF184 is built to follow the original application requirements for BMW performance models, supporting consistent fitment and dependable operation.
