Normal/OEM differentials It is more then likely that your OEM factory differential may have been designed primarily for regular city/highway driving. Most factory differentials are not designed for "sport" or "race" usage, therefore the design element caters more to basic function than performance application. On every car a basic differential is fitted to distribute the engine's power to the driving wheels, the basic differential gear supplies the power to the wheels which is loaded with the least resistance. This allows the car's wheels to run at different speeds in a turn with least resistance.

However, when a vehicle is cornering close to it's limit, the vehicle will exhibit body roll causing the vehicle to lean to one side, which will translate into the inside tire (s) losing forward traction and lateral grip. The wheels lift and cause excessive spin due to lack of downward force or weight distribution. This wheel spin is useless for acceleration until the tire (s) regain traction and start to gradually translate the power to the ground. A limited slip differential (LSD) is needed to alleviate this wheel- spin.

With racing or performance driving, your vehicle may demand more then what a factory differential is capable of providing. More traction, stability, quicker reaction times and higher cornering speeds are key factors in which improve your vehicles characteristics on the track. A KAAZ after market limited slip differential designed to cater around these needs will come handy and prove as a vital component on your vehicle.

Limited Slip Differential
An LSD is constructed slightly similar to the normal differential.

The pressure plate rings have the side gear, the pinion and the pinion gears locked inside and behind each pressure rings are a number of clutch plates. When torque is applied to the differential, the differential case will rotate and throw the pinion into the pressure ring cam. The pressure ring is then pushed out against the clutch plates thereby squeezing them together. This in turn causes the wheels to lock together, depending on the power applied. This effect limits wheel spin during hard cornering and applies power to the wheels evenly when more power is applied. On acceleration and deceleration, it provides even grip and on neutral power, it also free is up for less drag and easier turning.
