These components are complete constant velocity (CV) axle assemblies that transfer rotational power from the differential to the rear wheels while accommodating suspension movement. Each assembly includes pre-installed CV joints and protective boots, ready for direct installation.
These rear drive shafts transmit engine torque from the differential to the rear wheels, enabling forward and reverse motion. Their constant-velocity joints allow smooth power delivery through suspension travel and varying steering angles. Properly matched axles help maintain balanced torque distribution and stable handling; when worn, symptoms such as vibration, clunking noises, or uneven acceleration can occur.
CV axle assemblies endure torque loads and constant movement, and over time CV joints can wear, boots can split, and grease can leak. A failing axle may lead to clicking or popping sounds during cornering, vibration under acceleration, grease contamination, or clunking. Replacing worn axles with OE Match quality units restores correct drivetrain operation, smooth acceleration, and predictable handling.
Consider replacement if you notice any of the following:
• Clicking/popping when turning
• Vibrations at speed or under load
• Torn or leaking CV boots
• Clunking or inconsistent power delivery

The Genuine Porsche 9GT501201A / 9GT501201G rear driveshaft is an OE rear axle drivetrain component for selected Porsche 992 GT3 models. It transfers drive from the transmission / differential to the rear wheel hub, supporting smooth power delivery, suspension movement and reliable rear axle performance. Ideal for replacing a worn, noisy, damaged or failed rear driveshaft with Genuine Porsche quality.
Why Replace This Part?
The rear driveshaft is exposed to high torque loads, suspension movement, heat, road debris, vibration and weather conditions. Over time, the CV joints, boots or shaft assembly can wear or become damaged. A split CV boot can allow grease loss and contamination, which may quickly lead to CV joint wear or failure.
Replacing the complete assembly with a Genuine Porsche OE rear driveshaft helps restore correct rear axle drive operation and maintains the performance standards required for the Porsche 992 GT3 drivetrain.

High-quality GKN rear driveshaft for the Porsche 911 Type 992 GT3, designed as a premium replacement for Porsche OE references 9GT501201A and 9GT501201G.
The GKN GKND13208 complete driveshaft assembly transfers engine torque from the transmission and differential to the driven rear wheels while allowing for continuous suspension movement and changes in driveshaft angle.
Designed for installation on either the left-hand or right-hand side of the rear axle, the same driveshaft can be used for both positions.
Porsche reference 9GT501201G supersedes the earlier 9GT501201A reference.
GKN Automotive is one of the world's leading specialists in constant-velocity joint and sideshaft technology. Its aftermarket drivetrain components benefit directly from the company's OE engineering expertise and are designed to provide dependable torque transmission, durability and excellent Noise, Vibration and Harshness performance.
Why Replace a Worn Drive Shaft?
The driveshaft and CV joints operate under considerable load and are subjected to constant movement as the vehicle accelerates, brakes and travels over changing road surfaces.
Over time, wear or damage can occur to the CV joints, shaft, boots or associated components.
Possible symptoms of a worn or damaged rear driveshaft include:
• Clicking or knocking noises
• Vibration during acceleration
• Shuddering through the vehicle
• Excessive driveline play
• Noise when turning
• Damaged or leaking CV boots
• Grease loss around the CV joint
• Mechanical noise under acceleration or regenerative load.
Replacing a worn assembly with a complete quality GKN driveshaft helps restore smooth and reliable torque transmission.
PLEASE NOTE:
- The surcharge for this reconditioned part will be refunded when the exchange unit is received and approved by us and the relevant manufacturer.
- Please note, surcharge refunds often take an average of 6 to 8 weeks to be approved by the manufacturer.
- Acceptance of the exchange part is at the manufacturer's discretion, based on the part being fit for reconditioning.
- All surcharges and exchanges are subject to our terms and conditions.
