ARB 170112 Differential Breather Kit for 4WD Off-Road Applications

Manufacturer

ARB

<p>Since 1975, ARB has stood as one of the most trusted names in off-road engineering, pioneering purpose-built equipment that transforms how enthusiasts approach extreme terrain. Founded after a challenging Cape York expedition inspired Tony Brown to hand-craft more robust roof racks and bull bars in his Melbourne driveway, the brand has evolved into Australia's largest manufacturer and distributor of 4x4 accessories, trusted by off-roaders worldwide. What began as a grassroots response to inadequate equipment has grown into a global benchmark for durability, innovation, and real-world performance.</p> <h3>Engineering Excellence for the Harshest Conditions</h3> <p>From the beginning, ARB's focus has never changed: quality, reliability and practicality above all else, and today that same philosophy drives everything they do, with advanced technology, precise engineering and rigorous testing ensuring products perform in the harshest environments. The brand's commitment to research and development has yielded breakthrough technologies that have redefined what off-road equipment can withstand. In the late 1980s ARB acquired Old Man Emu and introduced the Air Locker to America, establishing product lines that remain industry standards decades later.</p> <h3>Front-End Protection and <a href="/982-arb-bumper-1340">Bumpers</a> That Define Durability</h3> <p>ARB's <a href="/982-arb-bumper-1340">bumper</a> systems represent the pinnacle of front-end protection engineering. These aren't cosmetic additions—they're fully integrated protection systems designed to absorb impacts from wildlife strikes, shield critical components during rock crawling, and provide mounting points for recovery equipment. Engineered with airbag compatibility and crash-tested to ensure they don't compromise vehicle safety systems, ARB bumpers balance aggressive capability with intelligent design. Whether navigating technical trails or preparing for expedition-length journeys, these bumpers serve as the foundation for a properly equipped adventure rig.</p> <h3>Air Management: <a href="/982-arb-tire-air-compressor-kit-52225">Tire Air Compressor Kits</a> and Beyond</h3> <p>Proper tire pressure management can make the difference between getting stuck and conquering challenging terrain. ARB's <a href="/982-arb-tire-air-compressor-kit-52225">tire air compressor kits</a> deliver reliable on-board air for adjusting pressures on the fly, enabling drivers to air down for traction in sand or mud, then re-inflate for highway travel. ARB has consistently pushed boundaries, introducing groundbreaking products like the recent Brushless Air Compressor, showcasing the brand's commitment to evolving technology. These systems also power air lockers, inflate camp gear, and support pneumatic tools—making them invaluable for serious off-roaders.</p> <h3>Illuminating the Trail: <a href="/982-arb-off-road-light-15431">Off-Road Lights</a></h3> <p>When daylight fades, quality lighting becomes a safety essential. ARB's <a href="/982-arb-off-road-light-15431">off-road lights</a> utilize advanced LED technology housed in pressure die-cast aluminum bodies that double as heat sinks, ensuring consistent performance during extended night driving. From spot beams that punch through darkness on high-speed desert runs to flood patterns that illuminate campsite work areas, these lights are engineered for the temperature extremes and vibration that define off-road use. Hybrid optic designs maximize beam efficiency while minimizing power draw—critical considerations for vehicles with limited electrical capacity.</p> <h3>Complete Systems Approach</h3> <p>Beyond individual products, ARB takes a systems approach to vehicle preparation. Their <a href="/982-arb-bumper-mounting-kit-1018">bumper mounting kits</a> ensure proper integration with vehicle-specific chassis designs, while <a href="/982-arb-suspension-kit-10922">suspension kits</a> leverage decades of Old Man Emu engineering expertise to optimize ride quality under load. Committed to developing the most technically advanced and innovative market offerings, ARB sets a global benchmark in the industry and continues to supply military, mining and government sectors around the world—a testament to the institutional trust the brand has earned.</p> <h3>The ARB Philosophy</h3> <p>ARB's philosophy has never wavered from its original course – quality, reliability and practicality above all else. This isn't equipment designed for showroom appeal or social media glamour shots. Every product undergoes validation in the field, tested against the punishing conditions of the Australian Outback and refined based on real-world feedback from explorers, miners, and rescue operations. From development to distribution across more than 100 countries, ARB continues to set the standard for adventure-ready equipment, proving that thoughtful engineering and uncompromising standards create products that simply work—when and where it matters most.</p>

Product Details

The ARB 170112 Differential Breather Kit is engineered to prevent water ingress into drivetrain components during off-road water crossings by replacing factory one-way breathers with a high-flow, zero-vacuum system to protect differentials, transmissions, and transfer cases. The shortfall with factory breathers is that driving through water crossings creates a vacuum caused by the drivetrain assembly being cooled rapidly by the water, which tightly closes the valve shut causing air to be instantly drawn into the assembly through the seals—often while seals are still submerged below water, leading to water contamination of the oil and possible damage to drivetrain components.

Key Features:

  • Anodized billet aluminum manifold is lightweight and resistant to the elements with four axle breather ports allowing for 1-4 breather lines to be connected
  • Includes splash-resistant ARB compressor air filters with washable high-flow sintered bronze filter cartridges
  • 8mm polyethylene tubing is flexible, oil-resistant, water-resistant, and heat-resistant
  • 8mm tubing selected over standard 6mm tubing to improve airflow and reduce the chance of oil blockages in long breather lines
  • Very compact design allows installation in virtually any location
  • Self-tapping screws included, with manifold mounting holes large enough for M6 (1/4 in.) bolt or stud mounting
  • 8mm push-in fittings make installation simple and fast

Complete Kit Includes:

  • Anodized aluminum manifold with 5 ports (4 x 1/8" BSP ports, 1 x 1/4" NPT port for air filter) and 2 mounting holes
  • 4 x 8mm-1/8" BSP push-in fittings
  • 3 x 1/8" BSP plugs for plugging unused ports
  • Air filter assembly
  • 8 meters x 8mm polyethylene tubing
  • 2 x self-tapping screws
  • 25 x cable ties

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. The central manifold features a high-flow air filter and allows up to four drivetrain assemblies to be vented to one central location—ideally somewhere on the vehicle that will be above the water level at all times. This kit is backed by ARB's 3-year warranty.

Best Price ! Quick and Easy Ordering. Thanks

Nice price!.. First time customer, so far so good

Best prices , great service, fast shipping, whats not to like? Will use Autoplicity again and again.

TOTALLY AWESOME

Hello, I did receive my order in a timely manner. But the tail pipe is not the correct one. So when I contact customer service, that will change this survey.

Quick and easy, so far satisfied and would recommend

If you like deep water crossings than this is what you need. It has 4 ports to connect your front and rear diffs, transmission and xfer case. You can mount it just about anywhere. Basically it's a snorkel for your drivetrain.

It was fast and easy thank you

Found what looks like the parts I need easily. Hopefully everything matches up.

efficient.

Great price, love those coupons, glad you're using paypal, I'll be looking for more things to buy. Best deal on the internet and brick and mortor stores.

Easy check out I like the PayPal option

Order several parts from Autoplicity for much less than the price I could find on any other site. With 3 days the first part was delivered to my door.<br><br>Excellent price and fast delivery time!

Great prices!

Organized website!

After searching Google Shopper for a Thule 45058 roof rack kit, I ran across Autoplicity.com was, by far, the lowest priced vendor for the product - so low that a local retailer offered to take 20% off their MSRP price but it still didn't compete with Autoplicity.com's price. Purchasing was a breeze and I look forward to receiving the rack soon.

Awesome prices on hard to find auto parts...quick shipping..A+!
