OS Giken Porsche Boxster Non-S (2nd Gen / 5MT Only) Super Lock LSD

The OS Giken Super Lock Limited Slip Differential (LSD) for your 2005-2012 Porsche Boxster Non-S with a 5-speed manual transmission is built with a unique multi-plate design that offers a significant improvement in traction and handling. This isn't just about putting power down; it's about making the car feel more connected and predictable when you're pushing it, especially out of corners. The Super Lock system is designed to engage smoothly under acceleration, but its real strength is how it locks up more aggressively as torque increases, ensuring both rear wheels are working together effectively.

What sets this OS Giken unit apart is its advanced clutch pack design. It uses a higher number of clutch plates than many other LSDs, which allows for finer control over lockup. This means you get a more progressive feel, reducing the tendency for some LSDs to feel abrupt or jerky. The internal components are made from strong, well-built materials designed for longevity and consistent performance, even under demanding use. Installation involves replacing the factory differential, and it's recommended to have this done by a professional mechanic who is familiar with differential work to ensure proper setup and backlash adjustments. This unit is specifically for the Boxster models that are NOT the 'S' variant and are equipped with the 5-speed manual gearbox.

When you're looking to get the most out of your Boxster's rear-wheel drive platform, especially if you track the car or enjoy spirited driving, an LSD like this OS Giken unit makes a notable difference. It helps put the power down more evenly, improving acceleration and stability. Make sure your car has the 5-speed manual transmission, as this differential is not compatible with other transmissions or the Boxster S models.
