This front differential lock is meant to be installed on the Jeep Wrangler TJ.
From the drop-down menu you can choose the differential, Dana 30 or Dana 44, the spline of the axle shaft and the final ratio to the axle, choose the DANA44 if your Wrangler Tj is a Rubicon model, DANA30 for all the other models, if you do not know the exact model of the differential contact us and we will help you choose.
On DANA 30 which originally use 27 splines it is possible to make the BIGSPLINE upgrade and install a 30 spline differential, 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 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.
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.
