ARB Xtras Differential Breather Kit Extension – Expands ARB 170112 System to 4 Assemblies

Expand your differential breather system with the ARB Xtras for Differential Breather Kit. This add-on kit provides additional tubing and push-in fittings designed to work with the original ARB 170112 Differential Breather Kit, allowing you to connect up to four assemblies to the central manifold.

If you’re running multiple breathers — such as front differential, rear differential, transfer case, and transmission — this extension kit ensures all components are routed cleanly to the elevated manifold for improved protection against water, mud, and dust intrusion.

🔧 Key Features

• Designed to expand ARB 170112 Differential Breather Kit

• Includes additional air line tubing

• Push-in fittings for quick, secure installation

• Allows connection of up to four breather assemblies

• Helps protect drivetrain components during water crossings

• Clean, centralized routing to ARB manifold

🛠 Why Upgrade Your Breathers?

Factory breather lines are often mounted low on the axle housing, making them vulnerable during deep water crossings. Extending them to a higher, centralized location helps reduce the risk of contaminated gear oil and costly drivetrain damage.

ARB designs its breather systems specifically for harsh off-road environments, giving you confidence on the trail.

⚠️ Note

This kit is an expansion accessory and requires the original ARB 170112 Differential Breather Kit for installation.
