ARB - arbRD169 - Air Locker Differential for Dana 60HF, 35-Spline, 4.10 and Down

The world's premier traction aid, an ARB Air Locker(TM) 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.

The ARB arbRD169 Air Locker Differential is designed for Dana 60HF applications with 35-spline axle shafts and a 4.10-and-down ratio. Its pneumatically operated locking system connects both wheels directly to the rotation of the ring gear when activated, helping provide maximum available traction in demanding terrain. When unlocked, it operates like a conventional open differential for on-road driving.

Operation is controlled from the driver’s seat, allowing the user to engage the locker without leaving the vehicle. The two-piece design uses minimal moving parts for durability and reliability, while the steel-reinforced, elastomer-bonded annular seal is designed to handle extreme climatic temperatures. The patented timed locking mechanism provides high-strength engagement and fast unlocking.
