The ARB Differential Breather Kit is engineered to safeguard your vehicle's critical drivetrain components from the damaging effects of water and dust ingress. Essential for any 4x4 adventurer tackling water crossings, deep mud, or dusty trails, this kit ensures the longevity and reliable performance of your differentials, gearbox, and transfer case. This particular kit, featuring additional tube fittings, is designed to expand upon an existing ARB Differential Breather Kit or to provide supplementary components for a custom setup. It allows you to extend breather lines to a higher, protected location, preventing contaminated air or water from being drawn into these vital components as they heat and cool. Crafted with high-quality, durable materials, ARB breather systems offer a secure and reliable connection, maintaining the integrity of your drivetrain in even the most challenging off road conditions. Trust ARB to deliver proven performance and protection for your rig.Manufacturer Part Number: 170113Image is for reference only; actual product may vary by application.
