Frequently asked questions

Why should I fit diff and drivetrain breathers?

Factory breathers are often short and located low, which can let water and dust enter when the components heat up and cool down. Extended breathers relocate the vents higher and use filters to reduce the risk of water and contamination entering differentials, gearboxes and transfer cases, especially in off-road and water crossing use.

What is the primary benefit of installing the 2 Way Diff Breathers?

The primary benefit of installing the 2 Way Diff Breathers is to prevent water and debris from entering the differential and transmission. By relocating the breather point above the water line, you significantly reduce the risk of contamination during water crossings or muddy conditions, ensuring the longevity and reliability of your drivetrain.

How is the installation process for the 2 Way Diff Breathers?

The installation process for the 2 Way Diff Breathers is straightforward and can typically be completed with basic hand tools. The kit includes all necessary components, such as heavy-duty mounting fixtures and stainless steel screws, ensuring a secure fit. It is advisable to follow the included instructions carefully for optimal placement and functionality.

Are the 2 Way Diff Breathers compatible with lifted vehicles?

Yes, the 2 Way Diff Breathers are compatible with lifted vehicles. The design allows for flexibility in mounting height, ensuring that the breathers can be positioned above the water line regardless of your vehicle's lift. This makes them suitable for various off-road setups.

Can I use the 2 Way Diff Breathers on other vehicles?

While the 2 Way Diff Breathers are specifically designed for the Toyota Surf 4Runner KZN N120 / N130, similar systems can be adapted for other vehicles with appropriate modifications. However, it is essential to ensure that the mounting and breather height requirements are met to maintain functionality.

How often should I check or maintain the 2 Way Diff Breathers?

It is recommended to inspect the 2 Way Diff Breathers periodically, especially after off-road use or water crossings. Check for any signs of damage, blockages, or wear. Regular maintenance will help ensure optimal performance and prevent potential issues with contamination.
