When activated, it delivers equal drive to both wheels on an axle, allowing you to take full advantage of the available traction in all conditions. A standard 'open' differential is a compromise, designed to allow wheels to turn at different speeds on pavement. off road, this becomes a liability, as it directs all power to the wheel with the least grip, leaving you stranded. While a limited-slip differential (LSD) offers a partial improvement, it requires wheelspin to engage and never truly locks.

The ARB Air Locker overcomes this by solidly locking the axle at the flick of a switch, providing 100% traction instantly. This allows you to confidently tackle steep inclines, rocky obstacles, and slippery tracks. When disengaged, the Air Locker functions just like an open differential, maintaining safe and predictable handling on sealed surfaces.
