ARB Differential Breather Kit. Replaces the factory diff breather with a high-flow, zero-back-pressure breather system — relocates the breather port up above water-crossing level and keeps water out of the diff during deep crossings.

Key Specs

• High-flow, zero back pressure, zero vacuum design
• Includes fittings for front diff, rear diff, transmission, and transfer case
• Relocates breather ports to a single high-mounted position

Install Notes

• Requires removal of factory breathers on each drivetrain component.
• Route breather lines to a high-mounted termination point (inside engine bay or under hood).
• Essential for deep water crossings.
