Diff Breather Kit

Diff Breather Kit

Protect Your Drivetrain from Water Ingress

Why should you relocate your axle, transmission and transfer case breathers? During off-road driving, especially water crossings, internal temperatures drop rapidly. This sudden cooling can cause negative pressure inside the components, potentially drawing water in through seals – leading to costly damage.

Open System for Safe Pressure Equalization

The Bison Gear Diff Breather Kit allows you to relocate breather lines to a safe, elevated area where water can’t reach. This open system ensures unrestricted pressure equalization and eliminates the risk of vacuum that might pull in contaminants.

Quick and Easy Installation

The kit is designed for straightforward installation with no need for specialized tools. Compact and user-friendly, it’s ideal for DIY enthusiasts and professionals alike.

Compact Size

Its minimal footprint makes it easy to fit even in tight engine bays, ensuring compatibility with most 4x4 vehicles and overland builds.

Machined from Billet Aluminum

The main breather block is CNC-machined from solid billet aluminum for maximum durability, corrosion resistance and a rugged, premium look.

Resistant Factory-Grade Hoses

Included hoses are resistant to oils, fuel and harsh environmental conditions. Built to withstand off-road abuse, they guarantee long-term performance and safety.

Protect Your 4x4’s Vital Components

If you're serious about off-roading and water crossings, the Bison Gear Diff Breather Kit is a must-have. It provides peace of mind, protects key drivetrain components and is built to handle the toughest terrain.
