In Japan, KAAZ was founded in 1922 with the primary objective of providing customers with high-quality racing differentials. Based on a coherent system of design, development, manufacturing and sales, KAAZ delivers parts for motorsports and racing worldwide in an effort to help cars run faster and feel more comfortable. Developed from outstanding concepts and cutting-edge technology, KAAZ differentials far exceed that of the competition.

KAAZ differentials are designed and engineered to be used in competitive motorsport and feature 8 to 24 internal clutch plates.
- Ideal for fast road and track use
- Maximises power distribution to wheels that need it most under acceleration
- Assists in braking stability and smoother turn-in
- Locking rate adjustments
Each LSD is activated by pressuring the clutch plates which produce a very strong locking performance and superior response during performance driving.
A clutch-type LSD has pressure rings and friction plates inside the differential case. The LSD acts as a standard differential when a car is moving straight or the rotational difference between left and right wheels are similar. Once there is a rotational difference among wheels, the cross axis, which is set in the middle, will press the pressure rings, then the pressure rings will transfer the movement to the clutch plates. When all the clutch plates are engaged, both wheels are locked and the torque is transferred equally to both wheels.
The 1.5-way differential is recommended for most types of motorsports driving. On acceleration, the 1.5-way optimizes the performance, which is followed by a lighter lockup during deceleration for ultimate traction.
