ARB High Level Differential Breather Kit for Off-Road Drivetrain Protection
How the ARB Differential Breather Kit Protects Your Drivetrain
The ARB High Level Differential Breather Kit is engineered to prevent water, dust, and debris from entering your vehicle’s differentials, gearbox, and transfer case during challenging off-road conditions. By relocating the breather points to a high, protected position, this kit helps avoid the costly repairs and reliability issues caused by water ingress—especially during river crossings or deep mud. If you regularly tackle water hazards, overland routes, or dusty tracks, this kit is designed to keep your drivetrain internals clean and dry, safeguarding your investment and supporting long-term performance.
Who Should Choose This ARB Breather Kit?
This kit is ideal for 4WD owners, off-road enthusiasts, overlanders, and expedition drivers who demand reliable drivetrain protection. It is particularly valuable for those running ARB Air Lockers or performance differentials, as well as anyone who frequently encounters water crossings or deep mud. The universal design suits a wide range of vehicles, including popular platforms like the Ford Ranger Raptor and other ARB-equipped builds. If you want to minimise the risk of oil contamination and mechanical failure on remote adventures, this kit is a practical upgrade.
What Makes This ARB Kit Distinct?
Designed by ARB, a leader in 4x4 protection and off-road solutions
Central manifold supports up to four drivetrain assemblies—front and rear differentials, gearbox, and transfer case
High-flow, zero back pressure design ensures consistent venting and reduces vacuum risk
Flexible, oil and heat resistant 8mm polyethylene tubing for robust routing
Includes a washable, splash-resistant ARB compressor air filter for long-term reliability
Compact, anodised billet aluminium manifold for corrosion resistance and easy mounting
Kit contains all required fittings, tubing, and mounting hardware for a straightforward installation
Unlike generic breather kits, this ARB solution is engineered for demanding off-road use, with components selected for durability and ease of installation. The high-flow manifold and 8mm tubing help prevent oil blockages and ensure your drivetrain breathes freely, even on extended overland journeys.
Typical Use Cases and Compatibility Guidance
The ARB High Level Differential Breather Kit is suitable for most 4WDs and off-road vehicles with multiple drivetrain assemblies. It is commonly fitted to vehicles such as the Ford Ranger Raptor, Toyota Land Cruiser, Nissan Patrol, and other expedition-ready builds. The kit’s universal design allows it to adapt to a variety of axle, gearbox, and transfer case layouts. For best results, check your vehicle’s existing breather locations and confirm the number of assemblies you wish to protect. If your build includes ARB Air Lockers or other performance drivetrain components, this kit is a recommended upgrade to prevent oil contamination and maximise reliability.
Key Benefits for Off-Road and Expedition Drivers
Prevents water and dust from contaminating drivetrain oil during river crossings and mud runs
Supports up to four assemblies for complete drivetrain coverage
Reduces risk of costly repairs and downtime due to water ingress
Helps protect ARB Air Lockers and performance differentials
Simple, reliable installation with push-in fittings and included hardware
Installation and Maintenance Notes
The ARB High Level Differential Breather Kit is designed for straightforward DIY installation. The compact manifold can be mounted in most engine bays using the supplied self-tapping screws or standard M6 bolts. Flexible 8mm tubing and push-in fittings simplify routing to high points on the vehicle, ensuring breathers remain above water level. Periodically inspect and clean the washable air filter, especially after dusty or wet conditions, to maintain optimal airflow and protection. For complex builds or if you are unsure about compatibility, consult a professional installer or your vehicle’s service manual.
