Rear differential lock Jeep Wrangler JL

Add to cart

This rear differential lock is designed to be installed on the Jeep Wrangler JL.

From the drop-down menu you can configure the equipment of your off-road vehicle, selecting the type of axle, M220 for RUBICON model and M200 for others model.

If your JL off-road vehicle has a manual gearbox or LSD differential, please indicate it in the notes.

From the drop-down menu you can choose the differential and the splines of the axle shaft.

The kit includes the differential lock, air fittings, solenoid valve and buttons for the electric operation of the block.

The great advantage of this system is represented by the fact that the vehicle circulates with the free differential in road traffic, thus avoiding premature wear of the wheels or the risk of a sudden engagement of the block.

In off-road, when the situation requires it, the lock can be activated, 100% effective, in a tenth of a second simply by pressing a button, activation and deactivation with the vehicle stopped.

This ARB block is to be purchased in combination with a compressor capable of operating the block.

Contact us for any doubts about the model of the diff lock to be purchased.


How the arb 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 the pressure necessary to engage the differential lock constant.

The switches, which can be fixed on the dashboard, allow the locking 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.

When the device is deactivated, the compressed air comes out of the solenoid valve and small springs open the safety ring, thus freeing the differential.

The assembly does not present major difficulties as it works on the original axles by replacing only the differential housing
