ARB | DIFFERENTIAL BREATHER KIT

22.000 KWD

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 differential/axle breather is very important on your four-wheel drive vehicle because it vents the air pressure in drivetrain assemblies, including the differentials, transmission and transfer case. Under normal operations, these assemblies heat up and the air expands inside which increases the pressure, and when the drivetrain assembly cools down, the air inside contracts and creates a vacuum.

This kit is designed to eliminate these problems by providing a high flow, zero back pressure and zero vacuum breather system. This is achieved with the ARB compressor air filter within the central anodized billet aluminium manifold that allows all of the assemblies to be vented from one location on the drivetrain. Ideally, this location will be somewhere that is above water at all times. The kit comes with unique 8mm tubing (where most use 6mm tubes), which are essential for 4×4 applications where camber driving can cause oil to enter and block smaller breather lines.
