ARB ARBRD166 Air Locker Differential – Dana 60HD, 35-Spline, 4.56 and Up

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.

Brief Description: The ARB Air Locker Differential provides on-demand traction for challenging terrain. Its pneumatically operated locking system prevents the internal differential gears from rotating independently, tying both wheels directly to the ring gear for maximum available traction. When unlocked, it operates like a conventional open differential.

Key Features & Performance Benefits:

• On-demand traction: Provides 100 percent traction when activated without affecting on-road drivability or increasing driveline wear.
• Driver-controlled operation: Convenient activation from the driver's seat helps support slower, safer and more controlled driving.
• Durable construction: The two-piece design, steel-reinforced elastomer-bonded annular seal and minimal moving parts are designed for strength and reliability.
• Fast engagement and release: The patented timed locking mechanism provides high strength and ultra-fast unlocking.
