Using a pneumatically actuated locking system, the ARB Air Locker for Dana 60HD instantly locks both axle shafts together at the flip of a switch, preventing differential action and ensuring both wheels turn with the ring gear. When disengaged, it operates as a standard open differential, eliminating unwanted noise, handling issues, and driveline wear on the street.

Kit Includes:

  • ARB 60HD Air Locker Differential
  • Dash Activation Switch
  • Solenoid Valve
  • Air Line
  • Bulkhead Fitting
  • Air compressor required for operation (sold separately).
