ARB - arbRD119 - Air Locker Differential, 31-Spline, Ford 9-Inch Ring Gear

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 arbRD119 Air Locker Differential is a pneumatically operated traction aid designed for Ford 9-inch ring gear applications with 31-spline axles. When activated, the locking system prevents the internal differential gears from rotating independently, tying both wheels directly to the rotation of the ring gear for maximum available traction. When unlocked, it operates like a conventional open differential.

Operation is controlled from the driver's seat, allowing convenient engagement 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 withstand extreme climatic temperatures. The patented timed locking mechanism provides high strength and fast unlocking.
