Protect Your Drivetrain from Water, Mud, and Pressure Buildup Water crossings, deep mud, or long-haul overlanding can spell disaster for drivetrain components if pressure builds up or water gets in. The ARB 170112 Differential Axle Breather Kit eliminates the limitations of factory breathers by providing a zero back-pressure, high-flow breather system for your differentials, transmission, and transfer case. This kit replaces factory one-way breathers with a centralized manifold system that connects up to four driveline assemblies. Its a simple upgrade that can save you thousands in repairs. Kit Includes: Central manifold block with 4 ports Air filter assembly with dedicated port Push-in fittings Tubing (enough to run at least two assemblies) Screws, plugs, and zip ties for clean installation Expandable just add tubing/fittings to run up to four breathers Key Features: High-flow, zero vacuum / zero back-pressure design Centralized breather manifold keeps water and dust out Filters air coming in no more dirty breather ports Connects 2 to 4 drivetrain assemblies (diffs, trans, t-case) Ideal for lifted vehicles, water crossings, and dusty trails Built for reliability in extreme off-road conditions Part Number: 170112 Installation Notes: Mount manifold in high, dry location (engine bay recommended) Route tubing from diff/trans/t-case breather ports to manifold Use included air filter for clean intake air Add more tubing/fittings to run all four ports if needed Secure lines with included cable ties to avoid kinks or snags Frequently Asked Questions: Q: What does this kit protect against?A: It prevents water, mud, and contaminants from entering your differential, transfer case, or transmission via the breather ports. Q: How many components can I connect?A: The manifold has 4 ports, but the kit includes tubing for at least two. You can add more tubing and fittings as needed. Q: Do I need this if I never cross water?A: Yes even dusty, high-heat environments can cause pressure issues or contamination. This kit increases reliability across the board. Q: Can I reuse any factory parts?A: This kit is designed to replace factory breathers completely for best results. Part Number:170112 FREE SHIPPING TO THE LOWER 48!
