ARB - arbRD140 - Air Locker Differential, 35-Spline, Ford 10.25/10.5-Inch

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 arbRD140 Air Locker Differential is a pneumatically operated traction aid designed for Ford 10.25- and 10.5-inch differentials with 35-spline axle shafts and a 1.5-inch axle shaft diameter. When activated, the Air Locker 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 the vehicle to maintain traction while the driver remains focused on the terrain. 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 and rapid unlocking.
