The world's premier traction aid, an ARB Air Locker keeps you moving in any conditions. A flick of the switch instantly locks the differential at any moment, and the super-strong design allows activation at any speed so you can tackle the toughest terrain. With both wheels tied directly to the differential under lock, full off-road traction is preserved while open-differential street manners remain unchanged when the locker is disengaged.
