The ARB Air Locker is a driver-selectable, air-operated locking differential that delivers 100% lock the instant you need it and open-diff manners the rest of the time. This unit is built for the Toyota IFS front carrier with a 34-spline axle — so traction goes exactly where it is needed the moment a wheel lifts or a surface lets go.
Flip the switch and both wheels drive together for maximum grip climbing rocks, crossing ruts, or clawing out of mud and sand; switch it off and the axle behaves like a factory open differential for smooth, predictable on-road driving. It is the same proven Air Locker relied on by hard-core wheelers and expedition builds worldwide.
