The LuK 415116609 is designed as a direct replacement for Porsche OE reference 982105264B and 982105264C.

Specifically designed for Porsche vehicles equipped with the PDK transmission – option code 250, this dual-mass flywheel provides the critical connection between the engine and the wet dual-clutch transmission.

Its internal damping system helps absorb torsional vibration generated by the engine before it reaches the transmission. This supports smooth torque transfer, reduces unwanted drivetrain vibration and helps maintain the refinement and responsiveness expected from a Porsche 718.

The flywheel is particularly suited to the high-performance 4.0-litre naturally aspirated six-cylinder 718 models, where precise drivetrain operation is essential for both road and track use.

Designed for PDK Transmission

The 415116609 is specifically designed for Porsche models using the PDK dual-clutch transmission with a wet-clutch arrangement.

PDK uses two clutches to manage alternating gear sets, allowing extremely fast gear changes while maintaining efficient torque delivery.

The dual-mass flywheel works alongside the transmission to help isolate rotational irregularities produced by the engine.

Correct flywheel operation helps provide:
•  Smooth torque transfer
•  Reduced drivetrain vibration
•  Reduced transmission resonance
•  Refined low-speed operation
•  Smooth engagement of the PDK drivetrain
•  Reduced shock loads through the transmission

What Does a Dual-Mass Flywheel Do?

A dual-mass flywheel contains two rotating masses connected through an internal spring and damping system.

The primary mass connects to the engine crankshaft, while the secondary mass interfaces with the transmission.

Combustion pulses naturally create rotational vibration within the crankshaft. Instead of allowing all of this vibration to pass directly into the PDK transmission, the internal damping mechanism of the flywheel absorbs and controls a significant proportion of it.

This helps reduce:
•  Transmission vibration
•  Gearbox resonance
•  Drivetrain noise
•  Harshness during changes in engine load
•  Shock loading through drivetrain components

High-Performance 718 Application

The Porsche 718 GTS 4.0, GT4 RS and Spyder RS use high-revving naturally aspirated flat-six engines that place significant demands on the drivetrain.

The dual-mass flywheel therefore needs to combine reliable torque transmission with effective vibration damping.

The LuK 415116609 is designed to maintain the stock-style drivetrain characteristics required by these PDK-equipped Porsche applications.

LuK Drivetrain Technology

LuK specialises in clutch and flywheel systems and has extensive experience in dual-mass flywheel technology.

A correctly designed dual-mass flywheel helps separate engine-generated torsional vibration from the transmission while still providing efficient torque transfer.

The 415116609 provides a stock-replacement solution for owners wishing to retain the original operating characteristics of their Porsche PDK drivetrain.
