What is the benefit of the included 4.62 final gear?

The 4.62 final gear ratio is shorter than the stock gearing. This change means the engine will rev higher in each gear, resulting in quicker acceleration from a standstill and out of corners. It alters the car's overall gearing for a more performance-oriented feel.

Does this LSD require a specific break-in procedure?

Yes, OS Giken typically recommends a break-in procedure for their clutch-type LSDs. This usually involves a period of gentle driving and specific oil changes to properly seat the clutch plates. Always refer to the manufacturer's installation instructions for the exact procedure.

What is the difference between this and a viscous or Torsen LSD?

This is a clutch-type LSD, which uses friction plates to lock the differential. It offers a very strong and progressive locking action that increases with engine torque. This provides a more direct and predictable feel compared to viscous or Torsen differentials, especially under hard acceleration.

About this part

Product Details

The OS Giken Super Lock Limited Slip Differential (LSD) for your 1997-2005 Acura NSX (6-speed manual transmission only) is built with a unique multi-plate design that offers a very strong locking effect. This unit comes pre-assembled with a 4.62 final gear ratio, which is a notable change from the stock gearing. This combination is designed to significantly improve traction and put the power down more effectively, especially when you're pushing the car hard.

OS Giken is well-known for its advanced clutch-type LSDs, and the Super Lock series is a popular choice for serious performance applications. The design uses a progressive locking mechanism that engages more strongly as engine torque increases, providing a solid feel and predictable behavior. This means you get improved grip out of corners and a more stable platform under acceleration. The internal components are made from strong, durable materials, and the unit is assembled with precision to ensure smooth operation and longevity. The inclusion of the 4.62 final gear means you're getting a complete package that not only enhances grip but also alters the gear ratios for quicker acceleration.

When installing this LSD, it's important to follow the manufacturer's recommended break-in procedure to ensure the clutch plates seat properly. This will help maximize the performance and lifespan of the differential. Because this is a significant drivetrain upgrade, it's often paired with other performance modifications to create a balanced setup. This unit is specifically for the 6-speed manual transmission NSX models.
