ARB, Differential Breather Kit (High-Flow Manifold), Universal Fit

ARB Differential & Drivetrain Breather Kit

Protect your drivetrain from the silent killer of gears and bearings: water and dust contamination. The ARB Differential Breather Kit is a high-performance replacement for restrictive factory breathers. Most stock breathers use a simple one-way valve that can easily clog or fail, creating a vacuum that pulls water into your differentials, transmission, or transfer case during deep water crossings or temperature changes. This zero-back-pressure, zero-vacuum system ensures your drivetrain can breathe freely, maintaining constant pressure while keeping contaminants out.

The heart of the kit is a compact, anodized billet aluminum manifold that can be mounted high in the engine bay or cabin, far away from water and mud. It features four dedicated ports, allowing you to centralize the breathing lines for your front and rear differentials, transfer case, and transmission into one secure location. Equipped with a high-flow, splash-resistant air filter, this kit is the ultimate insurance for overlanders and off-roaders who don't let a river crossing stand in their way.

Features

• Centralized Manifold System: Anodized billet aluminum manifold provides a clean, organized hub for up to four drivetrain breather lines.
• Zero Vacuum Performance: Eliminates the suction effect that pulls water and grit through oil seals during sudden cooling (like entering a stream).
• High-Flow Splash Filter: Features a splash-resistant, washable air filter that ensures only clean, dry air enters your drivetrain assemblies.
• Expandable Design: The kit comes with enough high-quality tubing and push-in fittings for two assemblies, but can easily be expanded to support four.
• Versatile Mounting: The compact, lightweight manifold is designed to be installed in virtually any high-point location on the vehicle.
• Anodized Billet Construction: Built to withstand the harshest off-road environments without corroding or degrading over time.
• Push-In Fittings: Utilizes high-quality, leak-proof push-in fittings for a fast and secure installation without the need for specialized tools.
