The advantage of the ARB Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear the vehicle maintains maximum possible traction at all times. When unlocked, it operates just like conventional “open” differentials.

In addition to providing outright improvements to a 4×4’s off road capabilities, the Air Locker offers significant environmental benefits. When approaching difficult terrain, less reliance is put on momentum. An Air Locker equipped truck can be driven in a slower, safer and more controlled manner as a result of vastly improved traction. This style of driving greatly reduces the likelihood of incurring vehicle damage and lessens the environmental impact as well.
