Description
Protect your transmission and eliminate annoying cabin vibrations with the genuine LuK Dual Mass Flywheel Assembly. Engineered by Schaeffler—the global pioneer of dual-mass flywheel technology—this precision-balanced assembly integrates primary and secondary flywheel masses with an advanced internal arc spring damping system. High engine torque pulses and severe thermal cycles eventually wear out internal springs, causing loud idle rattles, clutch shudder, and drivetrain harshness. This heavy-duty replacement unit solves those problems directly. It absorbs crankshaft torsional vibrations completely, safeguards your manual or dual-clutch transmission from shock loads, and restores smooth factory powertrain operation.
Technical Parameters
| Category | Specifications & Technical Details |
| Dual-Mass Decoupling & Internal Arc Spring Matrix | Adopts primary / secondary dual-mass decoupling design with built-in high-performance multi-stage arc springs, 100% absorbing and filtering torsional pulse vibration output from the engine crankshaft. |
| High-Frequency Quenched High-Thermal Friction Face | The clutch contact working surface undergoes high-frequency induction quenching and precision surface grinding, featuring extremely high thermal crack resistance and friction wear resistance. It withstands extreme half-engagement sliding friction heat without deformation. |
| Stepless Axial/Radial Travel Limiter & Anti-Bottoming Design | Internally integrates a precision mechanical limit structure, preventing excessive spring compression during hard acceleration or heavy-load towing. Completely resolves launch impact bottoming noise. |
| Precision Dynamic Balancing & Low-Inertia Topology | Each unit undergoes high-precision computer dynamic balancing calibration before leaving the factory, minimizing residual rotational unbalance to prevent engine vibration during high-speed operation. |
| Precision-Matched Pilot Bearing & High-Temp Axial Support | The center bearing bore and locating pin holes undergo micron-level CNC precision machining, ensuring perfect concentricity with the transmission input shaft and preventing clutch judder caused by eccentric operation. |
Applicable Car Brands & Models
Typical warning symptoms include:
Idle Rattle / Metallic Knocking: A loud rattling or knocking noise coming from the bell housing when the engine idles in neutral, which usually disappears when pressing the clutch pedal.
Severe Drivetrain Vibration: Shaking or heavy shuddering felt through the floorboards or steering wheel during acceleration, especially at low RPMs.
Clutch Pedal Pulsation: A pulsating or vibrating sensation felt underfoot when lightly pressing the clutch pedal.
Engine Shutdown Clunk: A metallic clunk or jolt when turning the engine off.
No, resurfacing a dual-mass flywheel is strictly not recommended. Machining the friction face removes vital metal thickness, reduces thermal capacity, and alters the internal spring pre-load tolerances, which quickly leads to catastrophic flywheel failure.
While conversion kits exist, switching to a solid flywheel removes the vital torsional damping system designed by the vehicle manufacturer. This often results in significantly increased transmission gear rattle, harsh vibrations, and premature wear on synchronizers and transmission bearings.
Each LuK DMF assembly is treated with anti-corrosion oil, secured with heavy-duty retaining brackets, and packed in a reinforced, multi-layer Schaeffler corrugated master box with high-density foam edge protectors to withstand harsh international freight handling.
