LuK Clutch DMF Flywheels

The downsizing of modern passenger car engines enables reduced fuel consumption and CO2 emissions, but can also increase rotational irregularities and natural vibrations. Torsional vibrations transmitted to other components in the drivetrain diminishes comfort and may even lead to component damage, therefore effective vibration damping is essential. LuK dual mass flywheels (DMF) reliably dampen torsional vibrations in the powertrain and ensure high gearshift and driving comfort in all speed ranges. Unlike a conventional flywheel, DMFs consists of two masses which are mounted to rotate against each other. A damping system in the form of arc springs is integrated to almost completely absorb the torsional vibrations of the engine. Precisely matched to the respective vehicle, each LuK DMF enables low-speed driving and ensures lower fuel consumption, as well as reduced emissions. Order the proper size for your vehicle.
