Product Details

If you're looking to significantly improve the traction and handling of your BMW, this OS Giken Super Lock Limited Slip Differential (LSD) is a solid option. This unit is designed to replace the factory differential in a range of BMW models, including the E30 M3 (manual transmission only) and E34 525i, 530i, and M5 (automatic transmission only). By controlling the difference in rotation between the rear wheels, an LSD helps put power down more effectively, especially when cornering or on slippery surfaces. This means less wheel spin and a more stable, predictable feel when you're pushing the car.

The Super Lock LSD from OS Giken is known for its advanced internal mechanism that allows for a high degree of locking action. It uses a multi-plate clutch system that can be adjusted to suit your driving style and vehicle setup. This means you can fine-tune how aggressively the differential locks, providing a unique balance between street drivability and track performance. The unit is built with durable materials to withstand the demands of spirited driving and is designed for a direct fit into the specified BMW applications, simplifying the installation process for experienced mechanics. The BM091-HA part number is specifically engineered for these BMW chassis, ensuring proper integration with your existing drivetrain components.

When installing a limited-slip differential, it's important to use the correct gear oil recommended by OS Giken to ensure proper operation and longevity of the clutch plates. This differential is a significant upgrade for enthusiasts looking to maximize their BMW's performance potential. It's a well-built component that can make a notable difference in how your car accelerates out of corners and maintains stability under load.
