ARB Air Lockers

Shop ARB Air Lockers for selectable on-demand traction in off-road, overland, rock-crawling, and 4x4 applications. An ARB Air Locker replaces the factory differential carrier and uses compressed air to lock both axle shafts together when maximum traction is needed.

With the flip of a switch, an ARB Air Locker can engage to help keep both drive wheels turning through rocks, mud, sand, loose dirt, steep climbs, and uneven terrain. When disengaged, the differential returns to normal operation for predictable street driving and everyday use.

ARB Air Lockers require a compatible onboard air source, typically an ARB air compressor, to supply the pressure needed for engagement. Depending on the vehicle and axle application, ARB offers locking differential solutions for a wide range of trucks, SUVs, Jeeps, and 4x4 platforms.
