Differential Breather Kit

The ARB Differential Breather Kit (Part #170112) is a premium solution designed to protect critical drivetrain components—differentials, transmission, and transfer case—from water and dust ingress during off-road and overland adventures. Standard factory breathers often sit low and can become compromised in deep water or muddy conditions. The ARB kit relocates these breathers to a higher, safer location using high-quality fittings, hose, and filters.

Whether you’re tackling water crossings or driving in dusty environments, this kit ensures your vehicle's drivetrain stays sealed and vented properly — enhancing long-term performance and reliability.
