KAAZ Limited Slip Differentials

Kaaz limited slip differentials have the largest friction plate surface area of any limited slip differentials, which in turn makes a very robust, fast acting limited slip differential that is able to effectively and reliably transfer torque to the road.
The Kaaz limited slip differential offers up to 100% locking in a precise and progressive unit giving the driver complete confidence to exploit the limits of their car. If less lock is required, each Kaaz limited slip differential is easily adjustable to give the optimum lock for a particular application.

Kaaz have developed their limited slip differential technology for all vehicle configurations. Whether that be a rear LSD for a rear wheel drive car, a front LSD for a front wheel drive car or a full front, center and rear set up for a four wheel drive car. Many manufacturers four wheel drive systems still use open differentials for the front wheel drive. In these cases, putting a single front Kaaz limited slip differential on the car will give immediate benefits getting torque to the road through the front wheels.

What’s the benefit of having a Kaaz Limited Slip Differential ( LSD ) ?

A standard open differential attempts to distribute the power equally across both wheels, but will prefer to send power to the path of least resistance. Hence in a corner the outside wheel is turning faster so most of the power is transmitted through it. This enables the car to turn smoothly, but has a major downside. Since the open differential will send power to the wheel moving the fastest, if one wheel is struggling for traction, it will get all the power. This means it is easy to spin a wheel with an open differential and once spinning, all power will be lost to the other wheel. This can make it difficult to get power to the road when accelerating hard and can make for instability during acceleration.

The other big downside is on the race track. In a hard corner, if one wheel loses traction (e.g, it lifts off the ground) and power is being applied, the open differential will transfer all the power to the wheel with no traction, uselessly spinning it. This is effectively like taking your foot off the throttle mid-corner and could cause the car to spin. A Kaaz LSD gets over these problems by locking the driven wheels together when power is put down, but still allowing some slip for the outside wheel in the corner giving better traction under acceleration, more stable acceleration and power to all the driven wheels in a corner. More than that though, the Kaaz LSD will give more stable braking by locking or partially locking the driven wheels under braking. This adds up to a more secure stable platform with better ability to get power to the road, which ultimately means faster lap times.

Why is a Kaaz Limited Slip Differential ( LSD ) better than other LSDs ?

Kaaz limited slip differentials are designed to be a hardcore motorsport product with great driveability, but no compromise. The most important factor in determining how much torque an LSD can transfer, is the friction area between the clutch plates. The greater the friction area, the better the plates grip and therefore the more torque the LSD is able to transfer without slipping. Since friction causes heat, the Kaaz LSD also makes use of the maximum allowable plate sizes in order to distribute the heat evenly so the plates don’t overheat. The other key factor is that Kaaz uses a larger number of clutch plates than many LSDs and these clutch plates are of a high precision forged construction making them very light weight and tough. All this adds up to an LSD that is bullet proof and can consistently transfer power to the wheels time after time, allowing the driver to get the most from his vehicle.

What is the difference between a 1, 1.5 way or 2 way Limited Slip Differential ( LSD ) ?

These numbers refer to the operation of the cams within the Limited slip differential. A 1 way diff only provides lock between the wheels whilst accelerating. In a 1.5 way diff, there is a degree of lock during braking, as well as under acceleration. The braking cam is half the size of the acceleration cam - hence the term 1.5 way. This provides a degree of improved balance during braking, but with less effect than a 2 way LSD.
 
In a 2 way LSD, the braking cam is the same size as the acceleration cam, providing more lock under braking. This provides the most stability and balance under braking, although it can induce some understeer in corners.

Finally, no-one takes quality control more seriously than Kaaz.
The Kaaz concept is to employ the best materials, the most advanced machining techniques and the highest quality control standards.
