ARB Air Locker Differential for AMC Model 20 with 2.73 Ratio – Easy Locking System for Off-Road Performance

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 Air Locker Differential, part number RD187, provides superior traction control for a wide range of vehicles, including AMC Model 20 axles with a 2.73 gear ratio. Designed with a pneumatically operated locking system, this differential enables instant lock at the flick of a switch, allowing drivers to effortlessly adapt to challenging terrains. Its robust construction and minimal moving parts ensure maximum durability and reliability in extreme conditions, making it ideal for off-road enthusiasts and professional drivers alike. When engaged, the Air Locker prevents internal gears from rotating independently, forcing both wheels to turn simultaneously for maximum traction. When disengaged, it operates as a conventional open differential, providing smooth on-road driving and reducing driveline wear. This versatility allows for safer, more controlled driving in rough terrains, minimizing vehicle damage and environmental impact. The kit includes the Air Locker differential, activation switch, solenoid valve, air line, and bulkhead fitting for easy installation. Its steel-reinforced, elastomer-bonded annular seal withstands extreme temperatures, ensuring consistent performance in harsh climates. The patented timed locking mechanism guarantees ultra-fast unlocking and high strength, giving drivers confidence in their vehicle's traction capabilities. A compatible air compressor (sold separately) is required for operation.
