Description
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. Specially designed to work with diffs and ARB air lockers.
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.
Features:
- Specifically engineered to work with differentials and ARB Air Lockers
- Compact and lightweight design with push-in fittings for simple installation
- Four breather ports for multiple applications
- Mounting holes will accommodate M6 bolt or stud
- Splash resistant air filter with washable high flow sintered bronze filer cartridge
- Oil, water and heat resistant 8mm polyurethane tubing reduces likelihood of oil blockages
