The CTS Turbo rear differential carrier insert set is designed to reduce drivetrain movement and improve power transfer in Audi A4, S4, A5, S5, RS5 and Allroad B8/B8.5 vehicles.
Key features
- Greater stability: reduces rear differential movement for improved throttle response and handling.
- Quality construction: made from durable billet aluminium for high strength and long service life.
- Reduced drivetrain play: reduces drivetrain flex and improves shift precision and acceleration.
- Easy installation: can be installed with basic hand tools, and the set works with the factory rear differential carrier.
- No significant increase in NVH: the design is adapted to improve performance without a significant impact on comfort.
Driving benefits
- Improved power transfer: less flex in the rear differential bushes ensures that more power is transferred to the wheels.
- More predictable handling: improves rear-end stability, making fast cornering and launching more controlled.
- More durable design: reduces excessive movement that can cause premature wear of drivetrain components.
The set is suitable for drivers who want to improve the response and driving feel of their Audi B8 vehicles, including occasional track use, while retaining everyday usability.
