The world's premier traction aid, an ARB Air Locker keep you moving in all conditions. With the flick of the switch an Air Locker gives instant lock at any moment and its super strong design allows activation at any speed allowing you to tackle the toughest terrain. The advantage of the Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the internal 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 like a conventional open differential. An Air Locker equipped vehicle can be driven in a slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact.

Documentation
The ARB Air Locker for the AMC Model 20 rear axle provides driver-controlled, 100% selectable traction on demand, transforming your vehicle's off road capability without compromising on-road driveability.
Specifically engineered for AMC 8.875 inch rear axles, this Air Locker is designed to suit gear ratios of 2.74 and down, delivering equal drive to both wheels at the flick of a switch. With a 29-tooth input shaft and a shaft diameter of 31.8 millimetres, it ensures robust engagement when navigating challenging terrain.
Its high-strength construction includes a ring gear with an outer diameter of 225.6 millimetres, built to withstand the rigours of serious 4x4ing. When engaged, it eliminates wheelspin on slippery or uneven surfaces, allowing you to maintain momentum and control over steep inclines, rocky tracks, and muddy bogs. Disengaged, it operates as a standard open differential, ensuring safe and predictable handling on sealed roads.
