HF Differential Breather Kit (Axle/Drivetrain Breather Kit)

The HF 4x4 breather kit is designed to properly vent drivetrain components such as axles.

The manifold body is made of lightweight, anodized aluminum, allowing connection of two or four components. Its compact design makes it easy to install virtually anywhere in the vehicle. The kit includes all necessary mounting hardware.

The breather filter is interchangeable with HF or ARB compressor filters, features splash protection, and is reusable after cleaning. The included 8 mm polyethylene hoses are flexible, oil- and fuel-resistant. They help minimize the risk of air lines getting blocked by oil, freezing, or other issues.

The push-in fittings are designed for quick and simple installation, requiring no additional brackets or clamps.

This kit is ideal for vehicles that frequently cross long or deep water obstacles, protecting drivetrain components from water ingress.
