Nissan Patrol and Safari Diff Breather Extension Kit

Relocate the factory drivetrain breathers on your Nissan GQ or GU Patrol / Safari to a higher position in the engine bay.

This diff breather extension kit helps reduce the chance of water, mud and grit entering your drivetrain during river crossings, muddy tracks and wet off-road driving. Choose between a 2-port kit for the front and rear differentials or a 4-port kit that also extends the gearbox and transfer case breathers.

Vehicle fitment

To suit:

  • Nissan GQ Patrol Y60
  • Nissan GQ Safari Y60
  • Nissan GU Patrol Y61

If you have any questions please get in touch before ordering.

2-Port Diff Breather Kit

The 2-port kit extends the front and rear differential breathers.

Kit includes:

  • 1 × Mounting bracket and breather housing
  • 4 × Self-tapping mounting screws
  • 2 × Breather filters
  • 4 × Hose connectors
  • 20 × Cable ties
  • 6 Metres of 10 mm diff breather hose
  • Fitting advice

The supplied hose is enough for most GQ and GU Patrol/Safari installations. 

4-Port Drivetrain Breather Kit

The 4-port kit extends the front and rear differential breathers, gearbox breather and transfer case breather.

Kit includes:

  • 1 × Splash-protected mounting bracket and breather housing
  • 4 × Self-tapping mounting screws
  • 4 × Breather filters
  • 8 × Hose connectors
  • 20 × Cable ties
  • 8 metres of 10 mm breather hose
  • Fitting advice

The 4-port kit is the best option for vehicles regularly used for river crossings, mud driving or more serious off-road use.

Why Extend Your Nissan Patrol or Safari Diff Breathers?

As your vehicle is driven, the differentials, gearbox and transfer case heat up. This causes the air inside these components to expand and vent through their factory breathers.

When a hot differential enters cold water, the air inside cools and contracts quickly. If the factory breather is submerged at this point, the resulting pressure difference may allow water, mud or grit to enter the drivetrain.

Relocating the breathers higher in the engine bay provides a cleaner and drier location for them to vent. This helps protect your drivetrain oils and internal components during water crossings.

Protected Breather Housing

The supplied breather housing helps shield the filters from direct splashes, mud and dust inside the engine bay.

The cover can be easily removed when the breathers need to be inspected or cleaned.

Installation

Installation generally takes approximately one to four hours and can be completed using basic hand tools.

Depending on the exact vehicle and existing breather arrangement, drilling and tapping a thread may be required to install some fittings. Check the installation requirements before beginning, or contact us if you need advice.

Shipping & Dispatch

We know you’re keen to get your gear, and we’ll get your order moving as quickly as we can. Our target dispatch timeframe is 3–10 business days once your order has been processed.

  • Many of our products are ordered or built specifically for each order. Once stock arrives from the manufacturer or supplier, we’ll get it packed and dispatched, normally within 1–2 business days.

  • AJF FAB products are generally kept in stock and ready to go. If an item needs to be fabricated, we’ll get it into the workshop schedule as soon as possible. Fabrication can take around 1–2 weeks, depending on current workshop demand.

  • We’re constantly checking supplier availability and updating stock information as it becomes available. “In Stock” means the item is available in NZ, available from an overseas supplier, or expected to be available for dispatch within 10 working days, based on the best information we have at the time.

  • You’ll receive a shipping confirmation and tracking details as soon as your order is on its way, where tracking is available.

We’ll always do our best to keep things moving and keep you updated along the way.

Some products are shipped directly from our suppliers. While we work hard to keep our stock levels accurate, there are times when items sell out faster than expected or our suppliers run out before our website can update. In these cases, your order may be placed on backorder, which can vary with each supplier.

Stock Availability

In Stock means the product is currently available in New Zealand, available from an overseas supplier, or is expected to be available for dispatch within 10 working days, based on the best information available to us at the time of purchase.

We regularly update stock availability as new information becomes available from our suppliers. However, stock levels and supplier availability can change quickly, and there may occasionally be a delay between a change in availability and our website being updated.

If there is any significant change to availability or expected dispatch time after your order is placed, we will contact you with an update.

These delays are outside of our control, and while we always do our best to keep customers informed, we strongly recommend contacting us before placing an order if you need an item urgently or by a specific date and we'll be happy to confirm availability for you

If you call and we are unable to answer, please leave a message, as we are often busy in the workshop or assisting other customers. We will return your call as soon as possible.

Our team will always do everything we can to keep you updated and get your order to you as quickly as possible.

Please note that we do not offer refunds for change of mind.
