LuK 415 0071 10 Flywheel

LuK 415 0071 10 Dual‑Mass Flywheel (DMF)

The LuK 415 0071 10 is a high‑performance dual‑mass flywheel engineered for manual transmission vehicles. It combines precision engineering, advanced materials, and innovative design to deliver smooth power delivery, reduced vibration, and enhanced durability.

Key Design Features

• Dual‑Mass Construction: Two interconnected masses separated by a damping system that absorbs torsional vibrations from the engine. This results in quieter operation and smoother clutch engagement.
• High‑Strength Alloy Core: Made from a proprietary alloy blend that offers superior fatigue resistance while keeping weight low, improving overall vehicle dynamics.
• Optimized Geometry: The flywheel’s rim is engineered with precise curvature to match the torque characteristics of modern engines, ensuring optimal power transfer and reduced wear on clutch components.
• Integrated Bearing Interface: Features a robust bearing housing that supports high rotational speeds and provides long service life under varying load conditions.
• Pre‑loaded Clutch Plate Compatibility: Designed to work seamlessly with LuK’s range of clutch plates, providing consistent performance across different vehicle models.

Performance Benefits

The dual‑mass design offers several tangible advantages for drivers and mechanics alike:

• Reduced Engine Vibration: The damping system mitigates torsional oscillations, leading to a noticeably smoother ride.
• Improved Clutch Longevity: By absorbing shock loads, the flywheel protects clutch plates from premature wear and extends overall component life.
• Enhanced Acceleration Response: The optimized mass distribution allows for quicker torque transfer, improving throttle response during acceleration.
• Lower Noise Levels: The dual‑mass configuration reduces high‑frequency noise that can be transmitted through the drivetrain.
