OS Giken Porsche Boxster Non-S (1st Gen / 5MT Only) Super Lock LSD

If you're looking to get the most out of your 1997-2004 Porsche Boxster Non-S with a 5-speed manual transmission, especially when pushing it on the track or during spirited driving, upgrading your differential is a key step. This OS Giken Super Lock Limited Slip Differential (LSD) is designed to put power down more effectively, improving traction and handling characteristics. It works by controlling the difference in rotational speed between the rear wheels, which is crucial for maintaining grip during cornering and acceleration.

OS Giken is well-known for its advanced clutch-type LSD designs, and the Super Lock series is a popular choice for performance applications. This unit features a unique multi-plate clutch system that can be adjusted to your specific driving needs. The design allows for a high degree of lock-up, which means both rear wheels are driven more consistently, even under aggressive conditions. This helps prevent wheel spin and ensures that power is transferred to the pavement where it belongs. The construction uses well-built components designed for durability under demanding use, making it a solid option for drivers who want a noticeable improvement in their car's performance and responsiveness.

Installation of a differential like this typically involves removing the transmission and carefully replacing the factory unit. It's a job that requires specialized tools and knowledge, so we always recommend referring to the manufacturer's installation instructions or consulting with a qualified mechanic. Once installed, you should notice improved acceleration out of corners and a more stable feel when applying power. This differential is specifically built for the 5-speed manual transmission found in the Non-S Boxster models from 1997 to 2004.
