Another quality BOSS product.Comes with the following

1 x Stainless Steel Laser Cut Facia

2 x 1/8” Cone Silencer

2 x 5/16” x 1/8” thread brass tail

4 x 1/2”OD Tube Clip

8mtrs EPDM rubber hose.

10 x 130mm zip ties

2 x 3/4” Tek Screws for mounting facia.

This kit is made from quality materials.

EPDM rubber is SAE-J-200 Spec heat and weather resistant,

This allows it to carry more aggressive hydrocarbon based products at higher temperatures than standard NBR and SBR

rubber.

The breathers are -porous polyethylene silencers

Water Resistant

Rated to 145 psi and -15 - 100 deg C

Filtration threshold 75 micron

When drivetrain assemblies such as your vehicle’s differentials, gearbox and transfer case heat up under normal operation, the air inside expands and increases pressure. To vent this additional pressure, most factory differentials have a one way valve mounted to either the assembly itself, or on a short extension tube close by.

Unfortunately, when the drivetrain assembly cools down, the air inside contracts, creating a vacuum. When cooling occurs during a water crossing, these one way valves can draw water into the system, potentially causing expensive damage.

The BOSS Differential Breather Kit is designed to provide a high flow, zero back pressure, zero vacuum breather system to keep your drivetrain free of water. This is achieved with a central mounted manifold that will allow up two drivetrain assemblies to be vented to one central location, positioned high enough to avoid water during crossings.

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 vehicles is the Twin Diff Breathers Kit compatible with? ⌄

The Twin Diff Breathers Kit is designed to be universally compatible with most 4WD vehicles that have differential assemblies. It is particularly beneficial for those that frequently engage in water crossings or operate in harsh environments.

How do I install the Twin Diff Breathers Kit? ⌄

Installation involves mounting the stainless steel laser cut facia in a suitable high location on your vehicle. Use the provided Tek screws for mounting and connect the EPDM rubber hose to the differential assemblies. Ensure the breathers are positioned high enough to avoid water ingress during crossings.

What is the benefit of using EPDM rubber in this kit? ⌄

EPDM rubber is used in the Twin Diff Breathers Kit due to its superior heat and weather resistance compared to standard rubber types. It can handle aggressive hydrocarbon-based products at higher temperatures, ensuring durability and reliability in extreme conditions.

How does the filtration system work in the Twin Diff Breathers Kit? ⌄

The kit features porous polyethylene silencers that provide a filtration threshold of 75 microns. This ensures that any contaminants are filtered out while allowing for high flow and zero back pressure, preventing water from entering the drivetrain assemblies.

Can I use this kit for both front and rear differentials? ⌄

Yes, the Twin Diff Breathers Kit is designed to vent up to two drivetrain assemblies simultaneously. This makes it suitable for both front and rear differentials, ensuring that both are protected against water ingress during off-road conditions.

What maintenance is required for the Twin Diff Breathers Kit? ⌄

Regularly inspect the breathers and hoses for any signs of wear or damage. Ensure that the breathers are clear of debris and functioning properly to maintain optimal performance. It is also advisable to check the mounting points periodically to ensure they remain secure.
