  • ABOUT ARB 170112: The ARB Differential Breather Kit is designed to provide a high-flow, zero back pressure, zero vacuum breather system to keep your drivetrain free of water. This is achieved with a central high-flow air filter and manifold that will allow up to four drivetrain assemblies to be vented to one central location, positioned high enough to avoid water during crossings.
  • CONSEQUENCES OF NOT HAVING ARB 170112: When drivetrain assemblies such as your vehicle’s differentials, gearbox and transfer case heat up under normal operation, the air inside expands and increases pressure, not suitable for the vehicle. The ARB Differential Breather Kit is designed to provide a high-flow, zero back pressure, zero vacuum breather system to keep your drivetrain free of water.
  • HOW DOES DIFFERENTIAL BREATHER KIT WORKS: It uses a central high-flow air filter and manifold that will allow up to four drivetrain assemblies to be vented to one central location, positioned high enough to avoid water during crossings.
  • PREVENT WATER FROM CONTAMINATING COMPONENTS: The ARB Differential Axle Breather Kit eliminates water from contaminating the oil and damaging your drivetrain components by providing a high flow, with no back pressure, zero vacuum breather system.
  • ARB 170112 KIT INCLUDES: Differential Axle Breather / Incl. Manifold / 4 Ports To Connect Up To 4 Breather Lines 7 Air Filter Port / Air Filter Assembly / Push-In Fittings / Plugs / Tubing / Screws / Cable Ties

¿DO I NEED A DIFFERENTIAL BREATHER?

ARB 170112 DIFFERENTIAL BREATHER KIT is extremely important insurance for your 4WD if you drive through water. In essence, when you go through a puddle that is near or above diff height, you are dunking a hot differential into cold water, this aggressive temperature change can damage your vehicle.

    Customers are satisfied with the quality of the auto accessory. For example, they mention it's top notch, well-made, and easy to install. That said, they say it works great when off-roading and breaths better than the OEM breather caps.

Some say that the filter and block can be easily mounted near the side wall in the engine bay. Overall, most are satisfied with the ease of installation and function of the product.

    12 customers mention6 positive6 negative

    Customers are mixed about the fit of the auto accessory. Some mention that the fittings are nice and convenient as a direct replacement for their 4Runner's rear differential. However, others say that the axle housing fittings and the hose outer diameter are small and they had to use an adapter to get it to fit.

    "...four push-to-connect threaded hose connectors, which conveniently fit as a direct replacement for the 04 Nissan Xterra breather...." Read more

    "...The hose outer diameter is kinda small and i had to use a adapter to get it to fit. The hose its self is a pain to run...." Read more

    "...The factory breather pulls right out, and the included fitting is the same thread and installs easily...." Read more

    "...I think my OEM setup was just as good if not better. The smaller diameter hose kinked right at the barb and makes me wonder if it is pinched shut..." Read more

    Did the update on 4runner rear differential. Did not use the self threaded bolts that come in the kit. Bought an M6 bolt and bolted the manifold to an existing threaded hole in the passenger side of the engjne bay, next to the air filter. Comes with 4 plugs for two breathers but can buy extra plugs since manifold holds up to 4. Video overview on how to below.https://youtu.be/Ob6oHB7vaGE?si=2yMG20bfem79G_0o
