ARB Air Locker® system is a pneumatic locking
differential that is activated by a dash mounted switch.
A small charge of air, from an on board compressor,
activates the locker which in turn locks both axles
together providing 100% traction. When not activated,
the ARB® operates as an open differential and does not
have any adverse effect on driving or handling.
