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.

Historically, the core business of LuK—an abbreviation that, in English, stands for disc and clutch makers--is clutches, their associated systems, and powertrain dampers. LuK clutch slave cylinders have a long operating life and low-friction characteristics, thanks to the special design of the central seal, with a plastic reinforcement and the use of special lubricants. LuK offers both hydraulic concentric slave cylinders fitted within the bellhousing and external slave cylinders for lever-operated throwout bearings. All automatically adjust for clutch wear.

An increasing number of vehicle manufacturers are using double clutch transmission technology, enabling comfortable gear changes without interruption of traction power, while at the same time reducing fuel consumption and CO2 emissions. Like almost every clutch, the double clutch can also wear out. However, replacement is not possible without special tools. This is because the double clutch is firmly meshed in the gearbox bell and must be removed together with the gearbox. LuK RepSet 2CT clutch kits offer a unique repair solution for dry and wet double clutches. With a LuK kit and the corresponding special tool, repair shops can repair double clutches quickly and professionally. Besides the double clutch, LuK RepSet 2CT kits contain all the precisely matched components in OEM quality which are necessary for the replacement of the respective double clutch system. These include guide sleeves, retaining rings, fixing screws and lever actuators, or engagement levers and engagement bearings. Features to note: * For dry and wet double clutches * Includes all parts needed for the repair * OE quality and perfectly coordinated * Safe mounting due to simple installation instructions * High-quality special tool for the perfect repair
