Diff Breather Kit 4 Port – Toyota LandCruiser 60 70 80 100 105 200 Series
Stop your diffs turning into milkshakes after river crossings, deep mud or beach runs on your Toyota LandCruiser 60 Series, 70 Series, 80 Series, 100 Series, 105 Series or 200 Series. This 4-port diff breather kit from Machter Auto Parts relocates all breathers (front diff, rear diff, transfer case & gearbox) high up on the chassis or roll bar, allowing air to vent freely while blocking water, mud and dust – a must-have mod for any serious off-roader, remote worker or 4x4 that sees real Aussie abuse on tracks, creeks, sand or corrugations.
Kit Includes
- 4 × high-flow extended breathers with splash-proof / filtered tops
- 4 × 1m lengths of high-temp reinforced braided hose (8mm ID)
- 4 × diff/transfer/gearbox-side fittings (push-in & screw-in – suits most Toyota axles)
- 4 × chassis/roll-bar mounting clips, zip ties & hose clamps
- Full installation guide with routing tips & photos
Why This Kit?
- Prevents water ingestion – no more milky diff oil or blown seals after creek crossings
- Blocks fine dust & mud – keeps gears & bearings clean, extends rebuild intervals
- Reduces pressure buildup – stops seals blowing out on steep climbs or high-speed runs
- Universal 4-port design – covers front diff, rear diff, transfer case & gearbox breathers
- Easy DIY install – 1–2 hours with basic tools, no special skills needed
- Essential insurance for solid-axle Cruisers – cheap mod that saves thousands long-term

Frequently Asked Questions
Which LandCruiser models is this 4-port diff breather kit compatible with?
This universal 4-port kit is designed to fit a wide range of LandCruiser models, including the 60, 70, 80, 100, 105, and 200 Series. It provides enough ports to cover critical drivetrain components like your front and rear differentials, transfer case, and gearbox.
Why do I need a diff breather kit for my LandCruiser?
Drivetrain components get extremely hot during operation. When you drive through a cold water crossing, the internal air rapidly cools and contracts, creating a vacuum that can suck water and mud into your gear oil through the factory breathers. This kit extends those breathers to a high point in the engine bay, keeping water out and your fluids clean.
Where is the best place to mount the manifold block?
The manifold block should be installed at the highest point possible within your engine bay—typically along the firewall or near the inner guard. Mounting it as high as possible ensures that even when tackling deep water crossings, your drivetrain remains safely sealed from water ingress.
Is this kit suitable for DIY installation?
Yes, it is designed for a straightforward DIY install. The kit includes the manifold, high-quality heat-resistant hose, and necessary fittings. If you are comfortable routing lines from your diffs and gearbox up to the engine bay, you can easily complete this upgrade with standard tools.
Does this kit improve the longevity of my LandCruiser's drivetrain?
Absolutely. Contaminated gear oil acts as an abrasive, accelerating wear on bearings, seals, and gear teeth. By preventing water and debris from entering the system, this kit helps maintain your oil's integrity, leading to smoother performance and significantly longer component life.
