TRE 4x4 Differential Breather Kit

Enhance Your Vehicle's Durability with the TRE 4x4 Differential Breather Kit

When driving, your vehicle’s drivetrain assemblies, including the differentials, gearbox, and transfer case, undergo a lot of stress. Under normal operation, these components generate heat, causing the air inside to expand and increase pressure. To manage this pressure, most factory differentials are equipped with a one-way valve, either directly on the assembly or on a nearby extension tube.

However, this system is not without its flaws. As the drivetrain assembly cools, the internal air contracts, creating a vacuum. This becomes particularly problematic during water crossings, as these one-way valves can inadvertently draw water into the system. Such water ingress can lead to costly damages and impair the functionality of your vehicle. To combat this issue, the TRE 4x4 Differential Breather Kit has been innovatively designed to offer a reliable solution.

How the TRE 4x4 Differential Breather Kit Works

The kit features a central high-flow air filter and manifold, capable of venting up to four drivetrain assemblies to a single, elevated location. This strategic positioning is crucial for ensuring the components stay dry, even during water crossings. The kit's design ensures there is no back pressure or vacuum, effectively keeping your drivetrain safe from water intrusion.

Out of the box, the 4 port TRE 4x4 Diff Breather Kit can connect to all four key drivetrain components - the front diff, rear diff, transfer case, and gearbox. It includes sufficient tubing and fixtures for the most common setup involving two differentials. For those needing to extend the protection to their transfer case and gearbox, additional tubing and fixtures are available separately.
