Luk DMF050 Clutch Flywheel

LuK DMF050 Dual Mass Flywheel Overview

The LuK DMF050 is a dual mass flywheel engineered for BMW applications that require precise drivetrain damping and OE-style fitment. Built around LuK’s original DMF design approach, it helps maintain smoother power transfer in the BMW M3 and BMW Z4 while supporting the drivetrain characteristics these vehicles were built around.

Compatible with 2001-2006 BMW M3 and 2006 BMW Z4, this LuK DMF050 flywheel is tuned for the application rather than adapted from a universal design. The result is a direct-fit clutch flywheel solution for drivers replacing a worn dual mass unit on select BMW performance models.

Key Features

• Dual mass flywheel design for drivetrain vibration control
• Flywheel diameter: 24.1 in. / 9.488 in.
• Flywheel inner diameter: 14.8 in. / 5.827 in.
• Flywheel cup depth/step height: -0.352 in. / -8.95 mm
• 113-tooth ring gear configuration
• Application-specific tuning for BMW M3 and BMW Z4 fitment
• LuK part number DMF050 for catalog and cross-reference lookup

Detailed Description

The LuK DMF050 clutch flywheel is designed as a dual mass replacement for select BMW models, including the 2001-2006 BMW M3 and 2006 BMW Z4. LuK develops DMF units to match the needs of each vehicle platform, helping preserve the drivetrain isolation and engagement characteristics expected from the original equipment layout. The listed dimensions, including the 24.1-inch flywheel diameter and 113 teeth, support accurate parts matching for BMW M3 and BMW Z4 flywheel replacement searches.

This part cross-references AMS Automotive 167005 for the same application. It also cross-references 50-2808 and 4150175100 for related catalog matching.

Common Replacement Reasons

• Excessive drivetrain vibration at idle or under load
• Noise from a worn dual mass flywheel assembly
• Shudder or inconsistent clutch engagement
• Wear-related driveline stress on BMW M3 and BMW Z4 applications
• Flywheel replacement during clutch service on select BMW models

Installation Notes and Tips

Verify the flywheel diameter, tooth count, and step height before installation to confirm the LuK DMF050 matches the vehicle’s original specification. Because this is a dual mass flywheel, proper inspection of the clutch system, release components, and related drivetrain parts is recommended during service. Confirm fitment against the vehicle’s year and model before installation on BMW M3 or BMW Z4 applications.

Quality Assurance

LuK is known for OE-level clutch and flywheel engineering, and this DMF is built to follow the original application-specific design philosophy. The LuK DMF050 is intended to replace the factory dual mass flywheel on confirmed BMW fitments with the dimensional and tooth-count specifications listed above.
