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 (P/N: 170112) 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 aluminum 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 4x4 applications where camber driving can cause oil to enter and block smaller breather lines.
