The ARB Differential Axle Breather Kit is designed to solve a common problem faced by 4WD enthusiasts—insufficient factory breathers on drivetrain assemblies. Stock breathers are often one-way valves with limited reach and poor protection from water, dirt, and pressure buildup.
ARB's high-quality solution replaces factory breathers with a high-flow, zero back-pressure, and zero vacuum system that vents air from differentials, transmissions, and transfer cases effectively. The compact billet aluminum manifold supports up to four drivetrain components, with push-in fittings and durable tubing included for two assemblies out of the box. Additional fittings and tubing can be added to connect up to four total.
Engineered for extreme off-road use, this breather kit reduces the risk of water or debris entering your drivetrain through compromised seals during deep water crossings or high-heat operation.
