This Convenient manifold is a fantastic way to prevent water and dirt from entering your differentials.

ARB differential breather kits are important to vent air pressure in drivetrain assemblies, and they eliminate the shortcomings of your factory breathers—especially when driving through water crossings. ARB units are high-flow, zero backpressure, zero vacuum breather systems. Each features a high-flow air filter within a central manifold that will allow 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. ARB differential breather kits are intended to replace your factory breathers and contain enough fittings and tubing to connect at least two drivetrain assemblies.


  • Axle breather manifold is machined from billet aluminum and anodized, making it lightweight and resistant to the elements
  • The manifolds have four axle breather ports, allowing for 1-4 breather lines to be connected
  • Very compact design, allowing them to be installed in virtually any location
  • The kits come with self-tapping screws, but the manifold mounting holes are large enough to allow mounting using an M6 (1/4 in.) bolt or stud, which is the common size in most vehicle engine bays
  • The air filters are the ARB compressor air filters, which are splash-resistant with washable high-flow sintered bronze filter cartridges
  • 8mm polyethylene tubing is flexible, oil-resistant, water-resistant, and heat-resistant
  • 8mm tubing has been selected over the standard 6mm tubing to improve the airflow and reduce the chance of oil blockages in long breather lines
  • 8mm push-in fittings make installation simple and fast
  • Kits include anodized aluminum manifold with 5 ports (breather lines and air filter) and 2 mounting holes, air filter assembly, fittings, plugs, polyethylene tubing, screws, and cable ties
