Key Features of the Portal Axles
- Comfort, comfort & comfort - now you can lift your vehicle and not sacrifice the on road ride quality.
- 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 high quality full synthetic
- 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.
Ground Clearance and Track
The portal transmissions have a vertical offset of 101mm (4"), this 101mm lift raises not only the body and chassis it also lifts the differentials by the same amount.
The portal transmissions increase the axle width by 100mm per side. Running positive 60mm offset 100/200 series LandCruiser rims moves the wheels back under the guards. The overall track of the vehicle is increased by 140mm.
The Portals are designed to run 35" tyres which gives correct steering geometry.
Reduced Bump Steer compared to Suspension Lifts
A suspension lift is not required, which keeps the control arms, and pan hard rods flat.
Many customers change to heavier springs when fitting the usual long list of off road accessories such as long range fuel tanks, water tank, drawer system, dual batteries, winch and the usual front and rear bar work etc. Good quality shock absorbers are a must due to the extra unsprung weight of the Portals and larger tyres, we have had good experience with both Ironman 4x4 and King shocks but can supply whatever shocks are specified.
One of the advantages of minimal suspension modifications is better handling due to no increase in bump steer. A softer ride can also be experienced with virtually flat control arms and better tracking due to, unchanged caster angle.
Driveline vibrations are a common experience when large suspension lifts are fitted. With minimal or no suspension lift along with reduced driveline angles, no drive shaft vibrations are experienced. This is due to the universal joints operating within their designed operating range.
Increased Driveline Strength
The torque load which is normally exerted on the differential, axles and constant velocity joints is transferred into the portal transmissions. The amount of load transferred is proportional to the gear ratio used in the transmission. The gear reduction of 1.16:1 offers a load reduction of 16%.
Oil is used for lubrication and is easily checked using the filler/level plug fitted on the differential side of each portal transmission. A drain plug is also fitted on the same side for ease of servicing. We use a high quality fully synthetic oil. You require about 3L of oil to service a Portal vehicle.
The portal transmissions are equipped with external breather ports, the extended breathers are connected and run up to the firewall. We also run your diff breathers up to the firewall as well.
ABS / ESC Equipped Vehicles
The function of the ABS & ESC systems in the Toyota 70 series remains unaffected.
Tyre Size and Offset Rims
With the Portal Axles fitted the rims required are a high positive offset rim with the LandCruiser 5 x 150 stud pattern. We have used wheels from ROH, CSA, Dynamic and genuine Toyota. Your options are as follows:
- 17 x 8 +60 offset
- 17 x 8 +50 offset
- 17 x 8 +47 offset
- 17 x 9 +47 offset
- 17 x 9 +40 offset
- 18 x 9 +47 offset
- 18 x 9 +40 offset
Tyres to suit the 17 x 8 inch rims are limited to 315/70/17, on the 17 x 9 rims you can run 315/70/17 or 35 x 12.5 R17 and on 18 x 9 rims you can run 305/70/18 or 35 x 12.5 R18.
Front Tyre Clearance
When fitting 35" tyres to Toyota LandCruiser it is necessary to trim the rear of the front flare to give clearance to turning tyres.
Wheel hubs and bearings
The front and rear wheel hubs and bearings are standard items as found in the 70 Series Toyota LandCruisers.
As there is an increase in the vehicles track of 70mm per side the tyres will protrude past the mud guards, to overcome this problem the portal axles are supplied with the necessary rubber flare and fixing screw kit on the front. On the rear we can supply fabricated guards for the cab chassis models.

PORTAL AXLES FAQ
WHAT DO THE PORTAL AXLE KITS COST?
The price of portal axles installed on Toyota Landcruiser VDJ 76, 78, 79 start from $33,500 (excluding wheels and tyres and suspension).
(As you can choose your preferred wheels and tyres and suspension kit, we can confirm the final price when you finalise your quote).
ARE PORTAL AXLES LEGAL IN ALL STATES OF AUSTRALIA?
Portal axles are legal in all states of Australia.
Pre-registration (new builds) are completed on SSM (second stage of manufacture).Post-registered vehicles can have portal axles installed with engineer certification. The engineer will follow the SSM approval for specifications.
CAN FIT THE PORTAL AXLE KIT MYSELF ?
You’re unable to purchase a portal axle kit and fit it yourself. All portal axle kits (both second stage and post registered) must be installed in-house here at Solve Offroad and certified prior to departure.
WHERE ARE THE PORTAL AXLE KITS MADE?
Portal axles are made right here in Australia! You are supporting Australian manufacturing when you purchase Marks 4WD Portal Axles. All components are manufactured in Victoria, Australia.
WILL THE PORTAL KIT ADD WEIGHT TO MY VEHICLE?
The weight the portal kit will add to your vehicle is approximately 120kg for the portal axle system itself, and approximately an additional 120kg for wheels and tyres.
SSM, WHAT DOES IT STAND FOR?
SSM stands for second stage of manufacture.
SSM only applies to new vehicles that have not 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 in 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 data base. 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.
