The ARB Air Locker for Dana 44 axles with 30-spline shaftsallows engagement at any speed and reverts to a standard open differential when disengaged. With the simple flip of a switch, the Air Locker instantly locks both axle shafts together, providing maximum control and traction in extreme off-road conditions.

This results in safer, more controlled driving on-road while offering unmatched performance off-road.
