Overview

The ARB Air Locker is a differential designed to provide 100 percent traction on demand. It allows for instant lock at any speed, enabling you to tackle tough terrain. When activated, the Air Locker prevents internal differential gears from rotating, ensuring both wheels turn together for maximum traction. When unlocked, it functions as a conventional open differential.
Show original supplier description
With the flick of a switch, this differential provides instant lock at any speed, allowing you to confidently navigate challenging terrain. Its pneumatically operated locking system prevents internal differential gears from rotating, thus preventing axle shafts from turning independently. This ensures both wheels are directly tied to the ring gear's rotation, maintaining maximum traction at all times. When unlocked, it functions as a standard open differential, offering versatility for on-road driving and minimizing driveline wear.
