LuK DMF040 Dual Mass Flywheel

The LuK DMF040 dual mass flywheel is an OEM-quality replacement component engineered to absorb engine vibrations before they reach the driveline. This advanced flywheel design features a primary section that bolts directly to the crankshaft and a secondary section onto which the clutch is mounted.

Key Features:

• Primary section dampens and isolates engine vibrations while preventing engine torque spikes from damaging the transmission
• 100% functionally tested to meet OEM performance specifications
• Consists of two masses mounted to rotate against each other with integrated arc spring damping system
• Developed by LuK as an original-equipment supplier with performance specifications crafted for individual vehicle applications
• Never resurfaced - all components are new to ensure maximum heat absorption capacity and service life

Every LuK flywheel component is engineered and built to original-equipment specifications, including the ring gear and dowel pins. By design, dual-mass flywheels cannot be resurfaced, making replacement with a new unit essential during clutch service to ensure proper clearances and optimal performance.
