OS Giken BMW E46 316t/320i (AT Only) / E90 320i (MT/AT) Super Lock LSD

The OS Giken Super Lock Limited Slip Differential (LSD) is built with a unique 2-way clutch system that engages both on acceleration and deceleration. This means you get improved traction and control when you need it most, whether you're powering out of a corner or braking into one. It’s designed to work with automatic transmissions for the 1996-1998 BMW 318i, and also fits the E90 320i in both manual and automatic configurations.

This differential uses a multi-plate clutch design, with 28 plates in total, allowing for a very smooth engagement that doesn't feel jerky or abrupt. The internal cam system can be adjusted to change the locking force, letting you fine-tune how the differential behaves to match your driving style or track conditions. OS Giken is known for its well-built drivetrain components, and this LSD is no exception, offering a solid option for BMW owners looking to enhance their vehicle's performance and handling.

Installation of a differential like this is a significant job, often requiring specialized tools and knowledge to ensure proper setup and backlash. It's recommended to have this unit installed by a professional mechanic experienced with performance drivetrain components. While this unit is designed as a direct replacement for the factory differential, it's always a good idea to consult the manufacturer's installation guide for specific details and torque specifications.
