Kaaz Corporation is the top brand name manufacturer and supplier of Limited Slip Differentials (LSD) for racing and street performance in Japan. *1.5-way LSD: works when accelerating. *The sensitive LSD will work even when the slightest torque is applied. *Increased ability to transfer power from the engine to the ground without loss. *The power acting on the plates is reduced so that abrasion on the plates are protected. *Increased number of friction plates greatly improves abrasion efficiency and heat capacitance of the plates. Longer plate wear life. *Not only the friction plates, but all parts of our LSD have been improved and made larger, so the overall strength of the main body is increased.
