Super 1.5-Way Rear Differential

The Kaaz Super SBN2635 is a 1.5-way limited-slip differential engineered for competition motorsports, offering a significant upgrade over factory viscous differentials. It is designed to react quickly and strongly, providing 100% locking under ex-factory preload, which is ideal for smooth, dry tarmac circuit use. The 1.5-way design offers optimal performance by maximizing power distribution to the wheels that need it most under acceleration, while also assisting in braking stability and smoother turn-in during deceleration. This differential utilizes 16 plates for handling medium to high power levels, ensuring durability and performance. The SuperQ variant, featuring WPC metal treatment, offers reduced chattering and smoother engagement for an enhanced driving experience, along with improved heat dissipation and longer wear life. No break-in process is required for SuperQ units, and they allow for locking rate adjustments. Included with the SBN2635 are a rear cover gasket, axle oil seals, and 2L of gear oil. It is important to note that this part number is for a 29 spline axle flange; for 30 spline Kouki S14 models, part number SBN2745 should be used. Buyers are advised to confirm their spline count before ordering. The Kaaz SBN2635 is compatible with a wide range of Nissan Skyline, Silvia, 180SX, Cefiro, and Laurel models from approximately 1988 to 1996, specifically those equipped with a factory viscous differential. Detailed fitment by year, trim, model, and engine is available in the product application chart.
