What is the benefit of the included 4.4 final gear ratio?

The 4.4 final gear ratio is shorter than the stock gearing. This means your engine will reach higher RPMs in each gear, resulting in quicker acceleration from a standstill and out of corners. It's a popular modification for performance driving.

What is a Limited Slip Differential (LSD) and why would I want one?

A Limited Slip Differential (LSD) is designed to send more torque to the wheel with better grip. Unlike an open differential, which sends equal power to both wheels and can cause one to spin freely if it loses traction, an LSD helps keep both wheels driving. This improves traction during acceleration, especially when cornering.

Does this LSD come with all necessary installation hardware?

This listing is for the OS Giken Super Lock LSD unit and the 4.4 final gear. Installation of a differential and final gear set is a complex procedure that typically requires new bearings, seals, and potentially other specialized hardware. It is strongly recommended to consult with a professional installer to determine all parts needed for your specific vehicle.

Product Details

If you're looking to get the most out of your 1997-2005 Acura NSX on the track or during spirited driving, upgrading the differential is a key step. This OS Giken Super Lock Limited Slip Differential (LSD) is specifically designed for the NA2 NSX with a 6-speed manual transmission, and it even includes a 4.4 final gear set to further tune your drivetrain's performance.

OS Giken is well-known for its high-performance drivetrain components, and this Super Lock LSD is a prime example. It uses an advanced multi-plate clutch system that allows for a very high locking coefficient, meaning it can transfer a significant amount of torque to both rear wheels even during aggressive cornering. This helps prevent inside wheel spin and improves traction out of turns, giving you more confidence and better acceleration. The included 4.4 final gear ratio is a popular choice for the NSX, offering improved acceleration compared to the stock gearing without sacrificing too much top-end speed. This combination can significantly change how the car feels when you get on the throttle.

Installation of an LSD and final gear set is a complex job that requires specialized tools and knowledge of drivetrain components. It's highly recommended to have this part installed by a professional mechanic experienced with performance differentials. OS Giken LSDs are built to last, but proper installation is crucial for their longevity and performance. This unit is designed as a direct replacement for your factory differential, but it's important to ensure all related components, like bearings and seals, are in good condition or replaced during the installation process.
