Air Locker Breather by ARB®. When drivetrain assemblies such as your vehicle’s differentials, gearbox and transfer case heat up under normal operation, the air inside expands and increases pressure. To vent this additional pressure, most factory differentials have a one-way valve mounted to either the assembly itself, or on a short extension tube close by. Unfortunately, when the drivetrain assembly cools down, the air inside contracts, creating a vacuum. When cooling occurs during a water crossing, these one-way valves can draw water into the system, potentially causing expensive damage. The ARB Differential Breather Kit is designed to provide a high-flow, zero back pressure, zero vacuum breather system to keep your drivetrain free of water. This is achieved with a central high-flow air filter and manifold that will allow up to four drivetrain assemblies to be vented to one central location, positioned high enough to avoid water during crossings.
The origins of ARB® can be traced back to Australia’s remote Top End, circa 1975. A region of vast distances and rugged terrain, it was fast becoming a Mecca for the nation's burgeoning 4WD community. However, the very environment that attracted 4 wheelers also wreaked havoc on their equipment – when driving in extreme conditions, only the best 4x4 accessories will do. Today, ARB is Australia’s largest manufacturer and distributor of 4x4 accessories. They also have an international presence, with an office in the US and an export network that extends through more than 80 countries around the globe. ARB's philosophy, however, has never wavered from its original course – quality, reliability and practicality above all else.
