The ARB Air Locker Differential for Dana 44 rear axles allows drivers to move slower, safer, and with greater control, reducing drivetrain shock, vehicle damage, and environmental impact. The Air Locker uses a pneumatically operated locking system inside the differential. When activated, the internal gears are fully locked, preventing independent axle shaft rotation and forcing both wheels to turn together. When disengaged, it operates like a conventional open differential for normal street use.

Kit Includes:

  • ARB Dana 44 Air Locker Differential
  • Dash activation switch
  • Solenoid valve
  • Air line
  • Bulkhead fitting

Notes: 

  • Air compressor required for operation (sold separately).

Tech Insight

ARB’s patented timed locking mechanism allows ultra-fast disengagement under load, reducing driveline stress while maintaining exceptional strength. The two-piece carrier design minimizes internal moving parts for maximum reliability under high torque and shock loads. A steel reinforced, elastomer bonded annular seal ensures consistent operation across extreme temperature ranges and harsh environments.

Selectable control means traction only when you need it with no compromise on-road, maximum confidence off-road.
