What does a differential breather kit do?

A differential breather kit replaces your vehicle's stock breather. It allows air pressure to vent from drivetrain assemblies like the differential, transmission, and transfer cases, preventing pressure buildup and vacuum.

How many drivetrain assemblies can this kit connect?

The ARB Differential Breather Kit 170112 comes with enough tubing and fittings to connect at least two drivetrain assemblies. You can purchase additional tubing and fittings separately to connect up to four assemblies.

Does this kit require special tools for installation?

The manufacturer description does not specify required tools. Refer to the ARB installation instructions for details on installation procedures and any necessary tools.

Product Details

A differential/axle breather serves the important purpose on a 4WD vehicle of venting the air pressure in drivetrain assemblies such as the differential, transmission and transfer cases. Many drivetrain assemblies are fitted with a breather from the factory. These factory breathers are usually a one-way valve mounted directly to the housing or remotely on a short tube. There are many short comings to this style and the ARB Differential Breather Kit is designed to eliminate these by providing a high flow, zero back pressure, zero vacuum breather system. The kit is intended to replace your factory breathers and contains enough fittings and tubing to connect at least two drivetrain assemblies. More tubing and push-in fittings can be purchased separately to connect up to four assemblies to the central manifold.
