The world's most highly regarded traction aid, an ARB Air Locker is a driver controlled locking differential originally designed to give serious 4 wheelers the traction needed to combat extreme off road terrain. When extra traction is required, the driver activates the Air Locker via a convenient dash mounted switch. Pneumatic pressure supplied by an on board air compressor engages ARB's patented locking mechanism within the Air Locker, thus preventing the wheels from turning independently. The Air Locker is deactivated by flicking a switch, returning the differential to normal. By far the most coveted locker in the world! Choose from front or rear lockers.

Air Lockers give you the traction you need, when you need it, all at the flick of a switch.
Provides 100% traction on demand without affecting on-road drivability or driveline wear
Vastly improved traction means less reliance on momentum, thus reducing the likelihood of vehicle damage and environmental impact
Easy, convenient operation allows the user to concentrate on the terrain without leaving the comfort and safety of the driver’s seat

Please note: This information is applicable to USA models only. This may change on some international models from year to year. Please check axle splines and ring gear bolts to confirm fitment before ordering.

ARB's locker test rig statically tests the Air Locker’s strength against the axle, with the goal being to always have the axle break before causing damage to the Air Locker.
