LuK DMF021 Dual Mass Flywheel
The LuK DMF021 is a dual mass flywheel engineered for BMW applications that require precise drivetrain damping and smooth power transfer. It is built around OE-style tuning to help reduce vibration and protect connected drivetrain components in demanding street use.
- Dual mass flywheel for controlled torsional damping
- Flywheel diameter: 24.1 in. / 9.488 in.
- Flywheel inner diameter: 15.3 in. / 6.024 in.
- Flywheel cup depth/step height: -0.362 in. / -9.2 mm
- 130-tooth ring gear
- Direct-fit application for BMW M5 and BMW Z8
OE-Style Drivetrain Control
LuK DMF021 is tuned for the specific demands of BMW M5 and BMW Z8 fitments, helping maintain smooth clutch engagement and consistent drivetrain behavior. As a dual mass flywheel, it is intended to isolate engine pulses more effectively than a solid flywheel, which can reduce stress on the transmission side of the drivetrain. This part number, DMF021, is also referenced by 50-2792 and 4150110100 for the same application.
What This Flywheel Helps Address
- Excess drivetrain vibration during acceleration and cruising
- Harsh clutch engagement and driveline shudder
- Wear related to torsional shock transfer through the gearbox
- Stress on engine mounts from uneven power pulses
- Potential crankshaft and transmission damage associated with solid flywheel conversion
Installation Notes
Verify flywheel diameter, tooth count, and step height before installation. This LuK DMF021 is listed for 2000-2003 BMW M5 and 2000-2003 BMW Z8, so confirm the vehicle’s clutch system and transmission specifications match the application before assembly. Follow factory service procedures for torque values, fastener replacement requirements, and clutch alignment.
Quality Assurance
LuK supplies OE-level drivetrain components, and this dual mass flywheel is fine-tuned for the listed BMW applications to support proper fit and function. Use the confirmed vehicle fitment and dimensional specifications to verify compatibility before installation.
