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 shortcomings 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.

Perfect addition to the ARB Safari Snorkel

I got my rear differential breather and rear locker actuator breather installed to go along with the ARB safari snorkel, which I also purchased from 4runnerlifestyle. It was a pretty simple installation over all, probably less than 1 hour, and the quality, like everything else ARB is top notch. The aluminum manifold was well machined and all the fittings fit perfectly. Between the snorkel and the breather, I now have a little extra piece of mind when traversing the back country. I ordered a cooper-Nickle plated 5/16 push to connect T-fitting and had some old rubber hose laying around that fit the outside diameter of both the new breather line and old actuator breather line to couple them together. Left some extra line partially rolled up near the differential to take into account axle drop.

ARB differential kit

Haven’t installed it, but looks like it’s straight forward. Just gotta fish the breather pipe and keep it away from the exhaust.

Works great and no modifications needed

I was able to install in under 30 mins mainly just figuring out where to mount and run the lines. Works great and looks great under the hood.

A must for every off roader and over lander.

Easy install and worth the added security for rear differential.
