LSD 431 K2 Limited-Slip Differential Gear

The LSD 431 K2 is a high-performance Limited-Slip Differential (LSD) designed to enhance your driving experience, especially in motorsports applications. Unlike standard open differentials found in everyday vehicles, the LSD 431 K2 ensures that power is effectively transferred to the road, regardless of the driving conditions. This means better traction, improved handling, and a more controlled driving experience.

Key Features

  • 2-Way Configuration: Offers both 1.5 and 2-way locking capabilities, allowing for versatile performance on various surfaces.
  • Ramp Angles: Comes with 55/20 and 55/55 degree ramp settings, providing customizable locking characteristics to suit your driving style.
  • Precision Engineering: Developed from nearly 50 years of motorsport experience, ensuring reliability and performance under pressure.

Benefits of the LSD 431 K2

This LSD system is engineered to limit the 'free-wheeling' of wheels that may slip or lose traction. By providing a controlled locking effect to the driving wheels, it maximizes power transfer to the ground. This feature is particularly beneficial in competitive scenarios where every bit of traction counts. The LSD 431 K2 not only enhances grip but also improves the overall handling dynamics of your vehicle.
