Overview

The ARB Air Locker is a pneumatically operated locking differential that provides 100% traction on demand. When activated, it locks the differential gears, ensuring both axle shafts turn together for maximum traction. When unlocked, it functions as a conventional open differential. This allows for controlled driving in challenging terrain without affecting on-road drivability. ARB utilizes advanced design and engineering, including CAD, CAM, and finite element analysis, to ensure product quality and durability. The two-piece design is ultra-durable with minimal moving parts, featuring a patented locking mechanism for high strength and fast unlocking. It includes a steel-reinforced elastomer bonded annular seal designed for extreme temperatures.

Part #: RD264

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 an conventional open differential. An Air Locker equipped vehicle can be driven in an slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact.
