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.
  • High-quality construction – made from durable billet aluminum for maximum strength and longevity.
  • Reduced drivetrain slop – minimizes drivetrain deflection, improving shifting precision and acceleration.
  • 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.
  • More predictable handling: Improves rear-end stability, making high-speed cornering and launches more controlled.
  • Stronger, more durable setup: Eliminates excessive movement that can lead to premature wear on drivetrain components.
