The CTS Turbo Rear Differential Carrier Insert Set is designed to reduce drivetrain movement and improve power transfer in your Audi B8 A4, S4, A5, S5, RS5, and Allroad.

Key Features:

  • Enhanced stability – reduces rear differential movement for improved throttle response and handling.

  • Easy installation – installs with basic hand tools and works with the factory rear differential carrier.
  • No significant NVH increase – engineered for performance without compromising comfort.

Performance Benefits:

  • Better power delivery: Reduces flex in the rear differential bushings, ensuring more power reaches the wheels.
