Driveshaft Flange Long for PDK Gearbox - CG225

This long driveshaft flange is a replacement transmission component for Porsche 981 Boxster S, Boxster GTS, Cayman S and Cayman GTS models equipped with the CG225 7-speed PDK gearbox.

Fits:

• Porsche Boxster 981 S / GTS 3.4L 2012-16
• Porsche Cayman S / GTS 3.4L 981 2013-16

Diagram Ref No 17 

The flange forms the connection between the gearbox output and driveshaft, ensuring engine torque is transferred to the rear wheels. It is designed to replace a worn or damaged original flange without requiring replacement of the complete transmission.

Vehicles equipped with the CG205 transmission use a different long driveshaft flange, reference 9G233220905.

Always confirm the gearbox code and vehicle VIN before ordering.

What Does It Do?

The driveshaft flange attaches to the transmission output shaft and provides the mounting point for the driveshaft.

As the gearbox delivers power, the flange rotates and transfers torque through the driveshaft to the rear wheel.

The long flange has a specific length and configuration to suit the CG225 gearbox assembly.

Why Is It Important?

A correctly fitted flange maintains a secure connection between the transmission and driveshaft.

A damaged or worn flange may cause:

• Vibration during acceleration
• Knocking or clunking from the drivetrain
• Excessive movement at the driveshaft connection
• Damage to the driveshaft mounting points
• Increased wear of associated gearbox components

Why Does It Fail?

Common causes include:

• Wear from repeated drivetrain loads
• Damaged splines or mounting surfaces
• Corrosion around the flange connection
• Loose or incorrectly tightened fixings
• Damage during driveshaft removal or gearbox repairs

When Should It Be Replaced?

Replace the flange if it becomes cracked, distorted or excessively worn.

It should also be inspected if the driveshaft connection develops excessive play or if damage is discovered during transmission servicing.

Checks & Installation

Inspect the gearbox output shaft, retaining ring, driveshaft connection and surrounding oil seal before fitting.

Ensure the replacement flange is correctly seated and secured according to Porsche's recommended procedures.

Professional installation is recommended.

Porsche 981 Boxster S / GTS & Cayman S / GTS PDK Driveshaft Flanges

The Porsche 981 7-speed PDK transmission uses driveshaft output flanges to connect the gearbox to the rear driveshafts. Selecting the correct flange is important because different gearbox versions require different components.

The long driveshaft flange is intended for Porsche 981 Boxster S, Boxster GTS, Cayman S and Cayman GTS models fitted with the CG225 PDK gearbox. Replacing a damaged flange helps restore a secure drivetrain connection and maintain reliable power transfer.
