Detailed Description

LuK DMF051 is a clutch flywheel designed as a dual mass flywheel for BMW Z4 vehicles. The unit is individually tuned for the application, helping manage engine torsional pulses before they reach the transmission. That matters in a BMW Z4 because drivetrain smoothness, clutch feel, and gearbox protection all depend on the flywheel’s ability to absorb vibration under load.

This part cross-references Sachs DMF91175 for the same application. If you are replacing a worn BMW Z4 flywheel, DMF051 is the OE-style reference to verify against your original unit by diameter, tooth count, and step height. The part number DMF051 is also commonly searched by buyers comparing BMW Z4 flywheel replacement options.

What It Helps Address

• Excess drivetrain vibration during acceleration and shifting
• Harsh clutch engagement or inconsistent pedal feel
• Wear on engine mounts caused by torsional shock
• Transmission stress linked to a worn flywheel
• Crankshaft damage associated with improper flywheel replacement

Installation Notes and Tips

Verify the original flywheel diameter, tooth count, and step height before installation. This BMW Z4 flywheel application includes a 113-tooth ring gear and a specified cup depth/step height, so matching the OE unit is important for proper clutch alignment and starter engagement. One listed fitment note applies to the 2004 BMW Z4 with non-sequential transmission, so confirm transmission configuration before ordering.
