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

The primary benefit is significantly improved traction and stability, especially during acceleration and cornering. The Super Lock design ensures a strong, consistent lock-up between the rear wheels, reducing wheel spin and enhancing the car's ability to put power down effectively.

Does this LSD require any special installation procedures or tools?

Yes, installing a limited slip differential is a complex drivetrain job that requires specialized tools and expertise. It is highly recommended to have this unit installed by a qualified mechanic experienced with Porsche transmissions to ensure proper setup and function.

How does the OS Giken Super Lock LSD differ from a standard clutch-type LSD?

The Super Lock LSD uses a unique cross-shaft mechanism that provides a more proactive and stronger lock-up under acceleration compared to many standard clutch-type LSDs. This design aims to minimize differential action under power, leading to more consistent drive to both wheels while still allowing for necessary slip during turns.

About this part

Product Details

This OS Giken Super Lock Limited Slip Differential (LSD) is designed specifically for your 2000-2004 Porsche Boxster S, as well as the 968 and Porsche G50 type manual transmissions from 1987 onwards. What you get in this package is the Super Lock LSD unit itself, ready for installation into your existing drivetrain. This isn't just about locking the differential; it's about fundamentally changing how your car puts power down, especially when you're pushing it hard.

The Super Lock LSD is known for its ability to provide a very strong lock-up under acceleration, which is crucial for getting the most out of your Boxster S. Unlike some other LSDs that might only engage under slip, the OS Giken unit is designed to lock up more proactively, ensuring both rear wheels are driven more consistently. This means improved traction out of corners, better stability under hard braking, and a more predictable feel when you're driving at the limit. The internal mechanism uses a unique cross-shaft design that allows for a high degree of lock while still permitting the necessary speed difference between the wheels during turns, avoiding the binding or chatter you might experience with simpler clutch-type LSDs. This advanced design contributes to a more comfortable driving experience on the street while offering serious performance benefits on the track or during spirited drives.

Installing an LSD like this is a significant upgrade for any performance-oriented Porsche. It requires careful setup and professional installation to ensure proper function and longevity. While this unit is built for performance, its robust design and the quality of OS Giken's manufacturing mean it's also well-suited for daily driving, offering a noticeable improvement in how your car handles power. If you're looking to maximize the performance potential of your Boxster S, especially for track days or autocross, this Super Lock LSD is a well-built component that can make a substantial difference.
