What is the primary benefit of a 4-disc LSD like this one?

A 4-disc limited-slip differential offers a more aggressive and immediate locking action compared to differentials with fewer clutch plates. This translates to improved traction during acceleration and cornering, making it ideal for performance driving and track use.

What is the recommended break-in procedure for this OS Giken LSD?

OS Giken typically recommends a specific break-in procedure for their multi-plate differentials. This usually involves a period of gentle driving with limited hard acceleration or cornering to allow the clutch plates to properly seat and mate.

Does this differential come with all necessary installation hardware?

The product listing specifies the differential unit itself. It is recommended to consult the manufacturer's installation guide or contact OS Giken directly to confirm if any specific installation hardware or specialized fluids are required and included.

Product Details

The OS Giken 4-disc clutch system in this limited-slip differential is designed for aggressive locking action, providing a significant mechanical advantage for performance driving. This unit is built specifically for the Ford 8.8-inch rear axle with 31 spline axles, making it a solid choice for enthusiasts looking to upgrade their vehicle's traction and handling capabilities. The 25/35-336-10-10s designation indicates specific internal settings that OS Giken tunes for optimal performance in demanding situations.

OS Giken is well-known for its high-performance drivetrain components, and this LSD is no exception. It's constructed with robust materials and features a multi-plate clutch design that allows for precise control over torque distribution between the rear wheels. This means improved acceleration out of corners and more predictable handling under hard acceleration and braking. The 4-disc setup offers a more immediate and forceful lock-up compared to 1.5-way or 2-way differentials with fewer plates, which is ideal for track use or spirited driving where maximum traction is critical.

When installing this differential, it's important to follow the manufacturer's recommended break-in procedure to ensure the clutch plates seat properly. This process is crucial for the longevity and performance of the LSD. While this unit is designed for performance, it's also built to be durable for its intended use. If you're rebuilding your rear end or looking to significantly enhance your vehicle's performance, this OS Giken LSD is a well-built option that offers a substantial upgrade in traction and control.
