Overview

The Nissan Differential Assembly, Viscous is a genuine OEM part designed for specific high-performance vehicle applications. This rear differential unit is engineered to provide reliable performance and direct-fit compatibility for factory drivetrain configurations.
Show original supplier description
This component is specifically compatible with several classic Nissan Skyline configurations, including the R32 GTS and the BNR32 GT-R. It is designed to work with vehicles equipped with manual transmissions and specific engine variants like the RB20DET and RB26DETT. Because this is a precise mechanical component, it is highly recommended that you consult your service manual, a professional mechanic, or a tuner to ensure correct part identification and installation for your specific vehicle configuration prior to purchase. As this is an original equipment manufacturer part, it maintains the integrity of the vehicle's drivetrain. It is important to note that compatibility provided in catalogs is a guide, and professional verification is always encouraged to avoid mismatch errors during the installation of rear-end components.
