OS Giken Ford 9in 31 Spline Rear End LSD (Requires Consultation for Custom Tune)

The OS Giken FD902-HA utilizes a unique 1.5-way clutch-type limited-slip differential design, featuring 24 locking points for precise control over power distribution to the rear wheels. This advanced system is specifically built for Ford 9-inch rear ends with 31-spline axles, offering a significant upgrade for performance-oriented vehicles where traction management is critical.

OS Giken is known for its robust and finely tuned drivetrain components, and this LSD is no exception. The 1.5-way action means it provides strong locking under acceleration to maximize grip, while allowing for a smoother, more predictable feel during deceleration and cornering, reducing unwanted oversteer. This careful balance is achieved through meticulous engineering and high-grade materials, ensuring durability and consistent performance even under demanding conditions. The 24-point engagement system allows for fine-tuning of the lock-up characteristics, enabling a custom setup tailored to your specific driving style and vehicle application. Because this differential requires a custom tune to achieve its full potential and ensure optimal operation with your vehicle's powertrain, consultation with a specialist is recommended before installation.

This LSD is a substantial upgrade for anyone looking to enhance their vehicle's handling and acceleration capabilities, particularly in applications involving high horsepower or competitive driving. Proper installation and setup are key to unlocking its performance benefits. Ensure you consult with a professional to dial in the settings for your specific needs.
