So what are portal axles?

Watch here

Marks 4wd Portal Axles

Portal axles are a 70 Series Toyota LandCruiser modification that raises the height of the axle and diff housing above the wheel hub, increasing ground clearance. A set of gears then connect the axle shaft to the wheel hub. Portal axles are the ultimate lift kit for your 4×4, giving you extra clearance to handle the toughest of terrain and look like a beast out on the tracks.

Getting Started with Portal Axles

  • Comfort, comfort and more comfort.
  • Lift your vehicle without sacrificing the quality of your ride on the road.
  • With the addition of 35″ tyres the total increase in ground clearance is approximately 150mm (6″) over standard.
  • When 35″ tyres are fitted, the differential to ground clearance is equivalent to having a standard live axle fitted with 43″ tyres.
  • Improved articulation is also experienced due to the increase in the vehicle track.Less body sway is also experienced due to the standard height springs and retention of the sway bars.
  • The 16% gear reduction offers this same percentage increase in strength to all of the transmission components from the CV joints back to the engine.
  • Each transmission holds approximately 450ml of oil.
  • The oil supplied with the portal assemblies is a high quality full synthetic oil.
  • The portal axle assemblies are supplied with breather hoses, manifold, and filters.
  • Portal vehicles have undergone brake and lane change testing and have easily passed all the required tests.

Portal axles are designed for the following Toyota LandCruiser models:

VDJ76, VDJ78, VDJ79GRJ71, GRJ76, GRJ78, GRJ79

Please contact the team for up to date pricing and information.

New unregistered vehicles that have a GVM of 3300kg's can be fitted with Portal Axles under SSM approval and are Legal in all States of Australia. New vehicles with a GVM of 3510kg's are awaiting Federal approval. We will keep you updated when approval's are granted.

Unfortunetly not. All portal axle kits must be installed in-house at Mick Tighe 4×4 & Outdoor and certified prior to departure. You’re unable to purchase a portal axle kit and fit it yourself.

A portal axle kit will approximately add 120kg in weight to your vehicle (for the portal axle system itself), and approximately an extra 120kg for wheels and tyres.

Note: Vehicle weights will always vary depending on what accessories may be added to the car.

The overall height of your vehicle once fitted with portal axles will vary between landcruiser models.

The vehicle heights below are based off the Toyota specifications for GXL models of the following vehicles:

  • Toyota Landcruiser VDJ76 Wagon 2090mm                      
  • Toyota Landcruiser VDJ78 Troop Carrier 2265mm
  • Toyota Landcruiser VDJ79 Dual Cab 2105mm
  • Toyota Landcruiser VDJ79 Single Cab 2105mm

(Please Note: The overall height measurement is taken from the highest point which is the top of the snorkel. It does NOT take into account suspension lifts/roof rack accessories or any other accessories that will add to the vehicle height).

Mark's 4wd has got the following tyre/wheel options approved through SSM:

- 315/70/17, 35x12.5R17, 305/70/18, 35x12.5R18
- 17x8 with +47 +50 +60 offsets
- 17x9 with +40 +47 offsets
- 18x9 with +40 +47 offsets

SSM is an abbreviation for the second stage of manufacture.

SSM only applies to new vehicles that have not yet been registered.

Manufacturers apply, test and meet all conditions put to them by the Department of Infrastructure, Regional Development and Cities. All ADRs (Australian Design Rules) must be adhered to. SSM approvals do not affect state and territory jurisdictional requirements. 

For example, Toyota Australia imports the Landcruiser as the first stage manufacturer. It meets all Australian design rule criteria.

A Marks 4wd portal axle system is then installed to the landcruiser pre-registration. We then apply to the department for the new VIN plate under our SSM approval. The department then issues the VIN plate after all quality control obligations have been met.

The vehicle is then recognised federally as having the equipment installed under the approval, and this is recorded on the Federal government database. The vehicle can then be registered in any state.

If you wanted to sell your vehicle then this process is very straight forward as it can be registered in any state due to the SSM fit-out.
