OS Giken Winters Quick Change IRS 10in 35 Spline 1.5-Way Super Lock LSD

This is the OS Giken Winters Quick Change Independent Rear Suspension (IRS) differential, specifically the 10-inch, 35-spline, 1.5-way Super Lock Limited Slip Differential (LSD) with part number WN435-HA15. This unit is designed for high-performance applications where rapid gear ratio changes are essential, often found in racing or specialized builds. The quick-change feature allows for adjustments to gear ratios without removing the entire differential, saving significant time during trackside maintenance or setup changes.

The Super Lock LSD mechanism is a key feature, offering a 1.5-way engagement. This means it locks up under acceleration for maximum traction and partially locks under deceleration, providing stability and predictable handling. The 35-spline count indicates a robust design capable of handling significant torque. OS Giken is known for its well-built drivetrain components, and this unit is no exception, utilizing strong materials and precise manufacturing to ensure reliability under demanding conditions. The 10-inch ring gear size signifies its suitability for applications requiring a larger, stronger differential housing.

When installing a unit like this, it's crucial to ensure proper setup and fluid levels. OS Giken recommends specific gear oil for optimal performance and longevity of the LSD mechanism. While this unit is designed for IRS applications, always confirm compatibility with your specific vehicle's rear suspension setup and axle shafts. This differential is a serious upgrade for those looking to maximize performance and adjustability in their drivetrain.
