A differential or axle breather vents air pressure from drivetrain assemblies on a 4WD vehicle, including the differential, transmission and transfer cases. While many assemblies come with factory breathers, these are typically one-way valves mounted directly to the housing or remotely on a short tube.
The ARB Differential Breather Kit is designed to replace these factory breathers with a high-flow system that provides zero back pressure and zero vacuum. It includes enough fittings and tubing to connect at least two drivetrain assemblies to the central manifold.
Additional tubing and push-in fittings can be purchased separately to connect up to four assemblies to the manifold.
Key features:
*The kit is intended to replace factory breathers and includes fittings and tubing for connecting at least two drivetrain assemblies.
