Engineered Performance for Audi, VW, Porsche & Skoda

Haldex LSC is fast! With instant activation independant on differential speed, Haldex LSC with PreX provides high torque transfer from stationery independant of any wheel rotation.
 
The Haldex LSC with PreX do not need any difference rpm to generate high torque transfer.
 
Haldex LSC is activated regardless of whether the input shaft is rotating faster or slower than the output shaft. This is a major advantage for the dynamic stability of the vehicle in acceleration or deceleration in combination with cornering or manoeuvring.
 
The torque transfer characteristics are controlled by the ECU, using the vehicle management information to adjust oil pressure via the throttle valve. With the controllable torque transfer characteristics of Haldex LSC, the vehicle performance does not need to be a compromise between traction, demanding high torque transfer, and manoeuvrability, demanding low torque transfer. The torque transfer is optimised for each driving situation - ensuring maximum safety and performance.
 
Torque transfer characteristics of the Haldex LSC. In normal driving conditions, the torque over the unit is controlled by the ECU. When a wheel start to spin, the coupling automatically and instantly stops the spinning. The maximum torque is set by the overload protection valve according to the vehicle manufacturer's specification.
