ARB Air Locker Dana 30 Differential with 27-Spline, 3.73 Ratio & Up - Part RD100

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 Dana 30 differential offers ultimate traction control for off-road enthusiasts and rugged vehicle applications. Designed with a pneumatically operated locking mechanism, this differential instantly locks the axle shafts when activated, providing maximum traction on challenging terrains. With the flick of a switch, you can engage or disengage the locker at any speed, making it ideal for overcoming mud, snow, rocks, and uneven surfaces. Its robust construction ensures reliable performance in extreme conditions, and the gear system prevents differential rotation, effectively turning both wheels in unison for superior grip. When disengaged, the Air Locker functions as a standard open differential, allowing for normal on-road driving and reducing driveline wear. This capability enables safer, more controlled driving in mixed conditions while minimizing environmental impact and vehicle damage through improved traction management.

Constructed with a steel reinforced, elastomer bonded annular seal, the ARB Air Locker is built to withstand the harshest climates. Its two-piece design minimizes moving parts, enhancing durability and reliability during demanding off-road adventures. The kit includes the differential, activation switch, solenoid valve, air line, and bulkhead fitting, providing a comprehensive solution for installation. For operation, an air compressor (sold separately) is required to supply pressurized air for engaging the locker, offering quick and responsive activation. The patented timed locking mechanism ensures ultra-fast unlocking, enabling seamless transitions between locked and unlocked states. Suitable for Dana 30 axles with a 27-spline, 3.73 ratio and higher, this product is compatible with Jeep Cherokee models from 1990 to 1997, making it a versatile upgrade for off-road vehicles.
