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.
It can be installed on all Nissan Patrol Y60/61 axles with 31 spline.
From the menu above, choose the side of the axle.
IMPORTANT: it is specified that these two bearings must be purchased for the front and rear blocks.
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 the lock to be activated and deactivated.
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.
IMPORTANT: ARB blocks are ordered upon customer request, so delivery times are variable.
