Protect your vehicle’s drivetrain during deep water crossings and muddy trail rides with the ARB Differential Breather Kit. This essential off-road upgrade replaces low-sitting factory breathers with a high-mount, filtered system that prevents water and contaminants from entering your differentials, transmission, or transfer case.

Reliable Protection for Deep Water and Mud
When a hot differential is submerged in cold water, it creates a vacuum that can suck water and dirt through factory breather valves, leading to oil contamination and premature gear failure. The ARB kit features a central manifold with a splash-resistant air filter, designed to be mounted high in the engine bay. This configuration provides a zero-vacuum, high-flow venting system that ensures your drivetrain "breathes" clean air even in the most demanding conditions.

Key Features

• 4-Port Manifold: The anodized billet aluminum manifold supports up to four breather lines, allowing you to connect front and rear differentials, plus your transmission and transfer case.
• Premium Filtration: Includes a high-quality, replaceable splash-resistant air filter to keep dust and moisture out of your oil.
• Universal Application: Designed to fit a wide range of vehicles including the Toyota Tacoma, 4Runner, Jeep Wrangler, Ford Ranger, and more.
• Complete Kit: Comes with 8 meters (approx. 26 ft) of high-quality polyethylene tubing and push-in fittings for a quick, secure installation.

Why It Matters
Factory breathers are often one-way valves that can easily clog with mud or fail when submerged. By relocating the breathing point to the highest possible location on the chassis, you gain peace of mind during river crossings and prevent costly drivetrain repairs caused by "milky" oil.
