The NISMO GT LSD Pro 1.5-Way Limited Slip Differential (Part No. 38420-RSS15-B5) is a high-performance mechanical differential designed to improve traction, stability and power delivery in Nissan rear-wheel-drive vehicles.

Featuring a multi-plate clutch-type design, this NISMO differential helps distribute engine torque more effectively between the rear wheels, particularly when accelerating out of corners. Its 1.5-way configuration provides LSD engagement under acceleration, with reduced engagement during deceleration, offering a balance of traction and predictable handling for performance driving, circuit use and drifting.

Developed for motorsport-inspired applications, the GT LSD Pro is engineered to provide consistent differential operation and improved driver control under demanding conditions.
