What is the main benefit of installing a Limited Slip Differential (LSD)?

An LSD helps improve traction by distributing power to both drive wheels, especially during acceleration and cornering. This reduces wheelspin and allows your Porsche 911 to put power down more effectively, leading to better handling and a more responsive feel.

Is this LSD compatible with automatic or PDK transmissions?

No, this OS Giken Super Lock LSD is specifically designed for Aisin manual transmissions only. It will not fit vehicles equipped with automatic or PDK transmissions.

What does the '28 locking tabs' mean for performance?

The 28 locking tabs in this multi-plate LSD design allow for a wider range of lock-up adjustability and smoother engagement compared to differentials with fewer tabs. This means you can fine-tune the LSD's behavior to better suit your driving style and conditions, from street driving to track use.

About this part

Product Details

The OS Giken Super Lock Limited Slip Differential (LSD) for your 2006-2013 Porsche 911 with the 3.6L or 3.8L Aisin manual transmission is built with a unique multi-plate design. This advanced setup uses 28 locking tabs, which is a notable increase over many other LSDs, allowing for a very smooth engagement and a wide range of lock-up adjustability. This means you can fine-tune how the differential behaves, whether you're on the street or pushing your car hard on the track.

OS Giken is known for its well-built drivetrain components, and this LSD is no exception. It's designed to handle the power and demands of the 997 generation 911. The Super Lock system is engineered to provide a significant improvement in traction, especially when exiting corners. By managing the difference in wheel speed, it helps put power down more effectively, reducing wheelspin and improving the car's overall stability and responsiveness. This is a substantial upgrade for anyone looking to enhance their Porsche's performance and driving dynamics.

This unit is specifically for Aisin manual transmissions and is not compatible with automatic or PDK transmissions. Proper installation by a qualified mechanic is recommended to ensure optimal performance and longevity. The adjustability of the OS Giken LSD allows for a personalized driving experience, making it a popular choice for Porsche owners seeking a more engaging and capable vehicle.
