Description
The ARB 170112 Differential Breather Kit is designed for off-road and overland enthusiasts who demand the best protection for their drivetrain. Factory axle, transmission, and transfer case breathers are often short and vulnerable, making them prone to ingesting water or debris during deep water crossings. The ARB breather kit solves this by relocating and elevating the breather ports using a high-flow, zero back-pressure manifold system.
This kit includes a compact, anodized billet aluminum manifold that supports up to four drivetrain components — such as front and rear differentials, transmission, and transfer case. The included splash-resistant air filter helps keep contaminants out while maintaining system airflow.
The system is designed for easy installation and includes high-quality push-in fittings, nylon tubing, mounting hardware, and zip ties. It fits a wide range of Toyota vehicles, including 4Runner, Tacoma, and Tundra, from the 1980s through 2015.
This is an essential upgrade for any 4WD used in muddy, wet, or dusty environments — offering long-term protection and peace of mind.
