Mounted at the transmission differential output, the flange provides the connection required to transfer engine power to the rear wheels.

Designed for compatible Porsche 992.1 manual gearboxes, it is an ideal replacement for worn or damaged original transmission components.

What Does It Do?

The short driveshaft flange connects the gearbox differential to the inner driveshaft joint.

It transfers rotational force from the transmission to the rear wheel, maintaining a secure mechanical connection during acceleration, deceleration and gear changes.

Why Is It Important?

A properly fitted flange helps maintain smooth and reliable power delivery.

A damaged flange may cause:

• Knocking or clunking during acceleration
• Excessive drivetrain vibration
• Movement around the driveshaft connection
• Increased wear to adjoining components

These symptoms may also result from worn driveshaft joints or gearbox mountings.

Why Do Driveshaft Flanges Fail?

Common causes include:

• Worn or damaged internal splines
• Repeated high-torque loading
• Loose or damaged mounting bolts
• Corrosion around mating surfaces
• Damage during gearbox or driveshaft removal

When Should It Be Replaced?

Replace the flange if it is cracked, distorted or shows excessive wear around the splines or mounting points.

It should also be inspected during driveshaft replacement, gearbox rebuilding or differential repairs.
