OS Giken Nissan GT-R R35 (TCD Rear) Super Lock LSD

This listing is for the OS Giken Super Lock Limited Slip Differential (LSD) specifically designed for the rear of the Nissan GT-R R35, identified by the TCD designation and part number NS251-HA. This is a high-performance differential engineered to significantly improve traction and handling characteristics for your GT-R. The Super Lock LSD is known for its ability to lock up effectively under acceleration, putting power down more evenly to both rear wheels, which is crucial for a car with the GT-R's power output. This helps reduce wheelspin and allows for more aggressive cornering and better stability under load.

OS Giken has built a strong reputation for producing durable and effective drivetrain components, and the Super Lock LSD is a prime example. It utilizes a unique multi-plate design that allows for a high degree of lock-up while still maintaining reasonable drivability on the street. The internal components are made from well-built materials designed to withstand the stresses of high-performance driving. Installation of an LSD is a complex job that typically requires specialized tools and knowledge of drivetrain components, often involving setting precise backlash and preload specifications. It's recommended to have this unit installed by a professional mechanic experienced with performance differentials to ensure optimal performance and longevity.

When considering an upgrade like the OS Giken Super Lock LSD, it's important to understand that it changes the way the car behaves, particularly during low-speed maneuvers and in tight turns, where you might notice a slight binding effect as the differential locks. However, on the track or during spirited driving, the benefits in terms of grip and control are substantial. This differential is a serious upgrade for GT-R owners looking to maximize their car's performance potential, especially if they plan on track days or competitive driving.
