ARB Air Lockers

ARB Air Locker - Selectable locking differentials

ARB Air Locker – Air Operated Locking Differentials for 100% Traction!


ARB Air Lockers were created to provide 100% traction on demand, without sacrificing any of your vehicle’s highway driving performance, these locking differentials employ a 12 volt air compressor designed to activate (and deactivate) a solid and durable locking mechanism inside the differential. This gives you the traction you need, when you need it, all at the flick of a switch, all within the safety and comfort of the driver’s seat.

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.
