Luk DMF112 Clutch Flywheel

LuK DMF112 Dual Mass Flywheel

The LuK DMF112 is a dual mass flywheel engineered for BMW applications that require precise drivetrain damping and smooth clutch engagement. Built around LuK’s OE-focused design approach, it is tuned to the vehicle application to help reduce the stress that can occur when a solid flywheel is used.

Compatible With BMW 135i, 335i, 335i xDrive, 335xi, 535i, and 535i xDrive applications from 2007-2010, this flywheel is a direct-fit option for drivers replacing a worn dual mass unit. The LuK DMF112 is also referenced by part number DMF112 for easy catalog matching.

Key Features

• Dual mass flywheel design for smoother power transfer and reduced drivetrain vibration
• Flywheel diameter: 24 in. (9.449 in.)
• Flywheel inner diameter: 15 in. (5.905 in.)
• Flywheel cup depth/step height: -0.362 in. (-9.2 mm)
• Number of teeth: 115
• OE-style application tuning for BMW 135i, 335i, and 535i fitments

Product Details

LuK manufactures this dual mass flywheel to match the demands of specific BMW drivetrain layouts rather than using a one-size-fits-all solid flywheel design. The DMF112 helps maintain the damping characteristics expected in the original system, which is important for clutch feel, gearbox protection, and overall driveline refinement. This part cross-references NDMF112 for the same application.

What It Helps Address

• Excess drivetrain vibration during acceleration and shifting
• Harsh clutch engagement and inconsistent pedal feel
• Wear related to drivetrain shock loading
• Noise and vibration transfer into the cabin
• Stress on engine mounts, gearbox components, and crankshaft interfaces

Installation Notes and Tips

Verify flywheel diameter, tooth count, and step height before installation to confirm the replacement matches the original specification. Inspect the clutch assembly, release components, and related hardware for wear before reassembly. Because this is a precision drivetrain component, installation should follow the vehicle service procedure and torque specifications for the exact BMW application.

Quality Assurance

LuK is known for OE-oriented drivetrain components, and this DMF is built to the application-specific standards expected for BMW 135i, 335i, and 535i models. The design focus is on preserving the damping function of the original dual mass flywheel and reducing the risks associated with solid flywheel conversions.
