What is the primary benefit of installing an OS Giken Super Lock LSD?

The primary benefit is significantly improved traction and handling. It ensures power is distributed more evenly between the rear wheels, preventing wheelspin and providing a more stable, predictable feel when accelerating out of corners.

Does this LSD require special break-in procedures?

Yes, like most multi-plate LSDs, it requires a specific break-in period with the correct differential fluid to properly seat the clutch plates and ensure optimal performance and longevity. Always refer to the manufacturer's installation manual for detailed instructions.

Is this LSD suitable for daily driving?

The OS Giken Super Lock LSD is designed for performance, but its multi-plate design aims for smoother engagement compared to some other LSD types. While it will be more noticeable than an open differential, it is engineered to be manageable for daily driving when properly installed and set up.

About this part

Product Details

This is the OS Giken Super Lock Limited Slip Differential (LSD) for your Nissan Skyline R34 with RB25DE/T engine or Silvia S15 with SR20DET engine, specifically for manual transmission models. If you're looking to significantly improve your car's traction and handling, especially during spirited driving or on the track, an LSD is a critical upgrade. It ensures that power is distributed more evenly between your rear wheels, preventing one wheel from spinning freely while the other struggles for grip. This results in a more stable and predictable feel when accelerating out of corners.

OS Giken is well-known for its high-performance drivetrain components, and their Super Lock LSD is a testament to that reputation. This unit utilizes a unique multi-plate design that offers a very strong locking effect, which can be adjusted to suit your driving style and track conditions. Unlike some other LSDs that can feel abrupt or jerky in daily driving, the Super Lock design aims for a smoother engagement while still providing maximum lock when you need it. The construction is solid, built to handle the stresses of performance driving. Installation involves replacing your factory open or clutch-type differential with this unit, which requires careful setup and typically professional installation to ensure proper gear meshing and backlash settings.

When installing this LSD, it's important to use the correct differential fluid recommended by OS Giken to break in the clutch plates properly and ensure longevity. This unit is designed to be a direct replacement for the factory differential housing, but it's always recommended to consult the manufacturer's installation manual for specific torque specifications and break-in procedures. Upgrading to this LSD will fundamentally change how your car puts power down, offering a more connected and capable driving experience.
