ARB Air Lockers
Advantages of an ARB Air Locker:
  • EASY TO USE: Dash-mounted push-button operation allows the driver to engage or disengage the ARB air locker at will. Locking takes place in 1/10th of a second.
  • RELIABLE: ARB Air Lockers use high grade aircraft alloy components that are up to twice as strong as stock differential components.
  • VERSATILE: ARB Air Lockers are Ideal for both street and trail use. Especially suited for use in front differentials.
  • AIR POWERED: On board ARB air compressor provides 80-105 psi for inflating tires, rafts, etc.
ARB's revolutionary differential uses compressed air from an on-board air compressor to lock both wheels of one axle so they work as one, providing equal driving power to each wheel. One compressor operates both front and rear ARB air lockers. Air Lockers are operated by the driver so they can be engaged or disengaged at will by pushing a dash-mounted button. This means there are no changes in handling or tire wear when they are unlocked, making the ARB Air Locker ideal for use in front differentials. No other locker or limited-slip differential offers these ARB advantages! ARB Air Lockers are the ultimate locker when it comes to getting a vehicle's power to the ground where it counts.
