This rear differential lock is meant to be installed on the Jeep Wrangler TJ.

From the drop-down menu you can choose the differential, Dana 35 or Dana 44, the spline of the axle shaft and the final ratio to the axle.

On DANA 35 which originally use 27 splines it is possible to make the BIGSPLINE upgrade and install a 30 spline differential while on the DANA 44 axle which originally uses a 30 spline differential it is possible to upgrade BIGSPLINE to 33 or 35 spline, in case you want to install a differential that allows the BIGSPLINE modification you must also purchase the axle shaft reinforced with the larger spline that you find here.

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.

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.

ARB LOCKER JEEP WRANGLER TJ

How the ARB Air Locker 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
