The ARB Dana 70/80 Air Locker is the world’s premier selectable traction device, engineered to deliver 100% traction on demand in the most demanding off-road and performance environments. This low speed carrier version is intended for performance applications and requires custom axle shafts to suit your specific axle assembly.

Using a pneumatically operated locking mechanism, the ARB Air Locker completely locks the differential when activated, preventing the internal gears from rotating independently. This forces both axle shafts to turn together with the ring gear, providing maximum traction exactly when it’s needed. When disengaged, the differential functions like a standard open unit, maintaining predictable handling, reduced driveline wear, and smooth street manners.

  • ARB Dana 70 & Dana 80 Air Locker differential
  • Dash mounted activation switch
  • Solenoid valve
  • Air line
