Description
The air locker is a differential designed for direct replacement of your existing one. It can be used either as a conventional differential or as a 100 % locked one — for either the front or the rear axle. When engaged, it locks both half-shafts and thus transfers the driving force equally (50% : 50%) to both wheels for maximum traction. The locking mechanism is controlled by the driver via a button on the vehicle’s dashboard. The front lock can be activated when driving on slippery surfaces with reduced grip and deactivated when driving on surfaces with good grip, in order to maintain optimal steering control. For safety reasons, the front lock cannot be used unless the rear one is already activated.

How it works
Because the locker is activated via compressed air, a compressor or other source of compressed air is required. The compressor is activated by the driver via a button on the dashboard. The pressure in the expansion tank is monitored by a regulator and operates in the working range of 5.9 bar to 6.9 bar. When the locker button is pressed, the pneumatic valve opens and allows the compressed air to reach the differential via an air line.
