About this part

Product Details

The OS Giken Super Lock Limited Slip Differential (LSD) for your 1995-1999 BMW M3 or 1998-2002 BMW Z3 is built with a unique multi-plate design that offers a significant improvement in traction and handling. Unlike some other LSDs that can be grabby or unpredictable, the Super Lock system is designed to engage smoothly under acceleration, providing consistent power to both rear wheels. This is especially noticeable when exiting corners, where it helps prevent wheelspin and keeps the car planted. The internal components are made from high-strength materials, ensuring durability for spirited driving and track use. This unit is specifically designed for manual transmission vehicles, ensuring a direct and proper fit for your E36 M3B or E40 M Roadster/Coupe.

What sets the OS Giken Super Lock apart is its ability to lock up to 100% of the torque, but it does so progressively. This means that even during aggressive driving, you get a predictable and controlled transfer of power. The design utilizes a special cam mechanism that adjusts the locking force based on the input torque, providing a seamless transition between open and locked states. This advanced engagement system is what makes it a popular choice for drivers who demand more from their drivetrain. The unit itself is well-built, with precision machining on all internal parts to ensure smooth operation and longevity. Installation will involve removing the factory differential and replacing it with this unit, which requires specialized tools and knowledge of drivetrain components.

When installing this LSD, it's important to follow the manufacturer's recommended break-in procedure to ensure the clutch plates seat properly. This will help maximize the lifespan and performance of the differential. OS Giken is known for its high-performance drivetrain components, and this Super Lock LSD is a testament to their engineering. It's a substantial upgrade that can change the way your BMW handles, especially when pushing its limits.
