9G131701500 PORSCHE Pdk Lsd Differential Unit Ring Pinion Set

Review PORSCHE 997 Pdk Lsd Differential Unit Ring And Pinion Gear Set Oem for 911 2009–2013

The Porsche 9G131701500 is a differential unit ring pinion gear set designed for Porsche 911 models from the 997 generation, produced between the years 2009 and 2013. This component is a crucial part of the car's powertrain system, as it is responsible for transmitting engine power to the wheels while also facilitating the torque vectoring function in PDK (Porsche Doppelkupplung) equipped vehicles.

The ring gear set forms the outermost part of the differential unit, and it is where the drive force from the engine is transferred via the prop shaft. The ring gear is secured to the differential housing, and it has 32 teeth that engage with the pinion gear located at the other end. The pinion gear, in turn, is connected to the output shaft that drives the wheels.

The 9G131701500 differential unit ring pinion gear set is made from high-strength materials to ensure durability and reliability under the demanding conditions of high-performance driving. The gears are manufactured using precise machining techniques to ensure accurate tooth profiles and tight tolerances, which translates to smooth and efficient power transmission.

The LSD (Limited-Slip Differential) functionality of this differential unit is achieved through the use of clutch packs located between the ring gear and the pinion gear. These clutches engage and disengage based on the difference in rotational speed between the two wheels, allowing for the transfer of engine torque to the wheel with the better traction. This results in improved stability, better cornering performance, and reduced tire wear.

In summary, the Porsche 9G131701500 09-13 997 911 pdk lsd differential unit ring pinion gear set is a critical component in the powertrain system of PDK-equipped Porsche 911 models from the 997 generation. It is responsible for transmitting engine power to the wheels while also facilitating the torque vectoring function through the use of a limited-slip differential. The high-strength materials and precise machining techniques used in its construction ensure durability, reliability, and efficient power transmission.

The Porsche 9G131701500 09-13 997 911 PDK LSD differential unit with ring pinion gear set is a high-performance component commonly used in the Porsche 911 PDK (Porsche Doppelkupplung or double-clutch) model cars from the 997 generation produced between 2009 and 2013. This differential unit is responsible for transmitting engine power to the wheels, providing improved traction and handling. Here are some pros and cons associated with purchasing this differential unit:

1. Enhanced Traction: The LSD (Limited Slip Differential) feature of this unit helps distribute engine power evenly between the wheels during cornering, improving traction and stability.

2. Smoother Transmission: The PDK (Porsche Doppelkupplung) transmission system offers smoother and quicker gear shifts, resulting in better acceleration and overall driving experience.

3. Increased Durability: The use of high-quality materials in the construction of this differential unit makes it more robust and long-lasting compared to factory units.

4. Improved Handling: The upgraded differential unit provides better grip and control, particularly during aggressive driving conditions.

1. High Cost: This differential unit is a premium aftermarket upgrade and can be quite expensive compared to the factory unit.

2. Complex Installation: The installation process of this differential unit can be complex and time-consuming, requiring specialized tools and skills.

3. Risk of Damage: Upgrading to a high-performance differential unit like this one also increases the risk of damage during aggressive driving, particularly if the vehicle is not properly tuned or maintained.

The Porsche 9G131701500 09-13 997 911 PDK LSD differential unit with ring pinion gear set is a desirable upgrade for those seeking improved traction, smoother transmission, and enhanced handling in their 911 PDK vehicles. However, the high cost, complex installation, and increased risk of damage are important considerations. Ultimately, this upgrade is best suited for enthusiasts who value performance and are willing to invest the time, money, and resources required for its installation and maintenance.

Before purchasing this differential unit, it is recommended to thoroughly research the installation process, ensure that the vehicle is properly tuned and maintained, and consider the potential costs, both financial and in terms of time and resources. It may also be beneficial to consult with a professional mechanic or Porsche specialist to determine if this upgrade is right for your specific vehicle and driving style.

Details:

The transmission bell housing was damaged and therefore the differential could not be tested. Item: pdk lsd unit w/ gears. See the photo below for illustration. Oe part #: 9G131701500.

Details can be viewed in the photos. Condition: this lsd and ring pinion gear set was removed from a 2011 911 GTS with 59k miles pdk transmission. It spun smoothly and locked up normally before removal. The gears are all intact and show no major wear.

Still not sure this part will fit your car. 09-13 Porsche 997 911 pdk lsd differential unit w/ ring and pinion gear set oem: stock #: 50485. Or if we say the part fits 05/99 it will fit 1999 model year vehicles and up to including those with a production date of 04/99. Which side does this part fit?, left driver side, right passenger.

Reference to driver/passenger side is for left hand drive cars, so RD vehicles UK/japan/Australia, etc. Please reverse the indicated. This is a used original BMW part. Rarely, large or difficult to package items will take a day two longer. Guaranteed good working condition.
