The great advantage of this system is represented by the fact that the vehicle in normal road traffic circulates with the free differential, thus avoiding the premature wear of the wheels or the risk of a sudden engagement of the block.
Off-road, when the situation requires it, the block can be activated, with 100% effectiveness, in a tenth of a second simply by pressing a button, inserting and disengaging when the vehicle is stationary.
The assembly does not present great difficulties as it works on the original axles replacing only the differential box.
How ARB's Air Locker Lock works:
the compressor (not included) releases the pressure necessary to lock the differential and is usually installed in a suitable position inside the engine compartment. The compressor is switched on automatically and is used to keep constant the pressure necessary to insert the differential lock. The switches, which can be fixed on the dashboard, allow you to start and stop the locking.
The insertion can also take place with the vehicle running thanks to the type of annular piston applied to the differential, but a reduced speed is recommended anyway.
When the device is switched off, the compressed air comes out of the solenoid valve and small springs open the safety ring, thus releasing the differential.
To make the order correctly, it is necessary to check if the original differential has 10 holes or 12 holes for fixing the bevel gear, unfortunately it is not possible to identify it only from the chassis number.
