The Toyota LandCruiser has built a strong reputation for its off-road prowess and robustness. However, LandCruiser owners who wanted to enhance their 70 Series vehicles with Marks 4WD Portal Axle kits faced a setback due to the reclassification of these vehicles as Light Trucks in the NB1 category. The wait is finally over! Starting from July 2023, the Marks 4WD Portal Axles have received official Federal Approval for pre-registration installation. This approval opens up a world of possibilities for new model LandCruiser owners, allowing them to take full advantage of the benefits offered by the portal axles and increasing the Gross Vehicle Mass (GVM) to 3950kg. Below we explore the exciting opportunities these portal axles bring to your LandCruiser build.
Unrivalled Lift and Tire Compatibility
The Marks 4WD Portal Axles provide an impressive 6" (150mm) lift under the axle, allowing for increased ground clearance and unmatched off-road capability. Engineered to accommodate 35" tires on 17" and 18" wheels, these axles enable you to conquer even the most challenging terrains with ease.
Enhanced Stability and Handling
One of the standout features of the Marks 4WD Portal Axles is their ability to deliver exceptional ride quality and stability, even with the increased lift and tire size. Thanks to the standard height springs and retained sway bars, less body sway is experienced, ensuring a comfortable and controlled ride on and off the road.
Uncompromised Articulation and Improved Track
By increasing the vehicle's track by 80mm, the Marks 4WD Portal Axles improve articulation, allowing your LandCruiser to flex and adapt to uneven terrain with greater ease. The wider track also contributes to enhanced stability during cornering, giving you more confidence in all driving conditions.
Powerful Gear Reduction
With a 16% gear reduction, the Marks 4WD Portal Axles offer a significant increase in driveline strength. This reduction in torque load on the differential, axles, and constant velocity joints ensures optimal durability and performance, even in the most demanding situations. The gear reduction also translates to improved crawl ratio, making it easier to navigate steep inclines and technical obstacles.
Reliable and Efficient Lubrication
Lubrication is a critical aspect of any axle system, and the Marks 4WD Portal Axles are designed with durability and ease of maintenance in mind. Each portal transmission holds approximately 400ml of high-quality, full synthetic 75w-90 GL-5 oil. With easily accessible filler and drain plugs, servicing these axles is a breeze. We recommend using Penrite Pro Gear 75w-90 GL-5 Full Synthetic Gear Oil for optimal performance.
Compliance and Legal Approval
The Marks 4WD Portal Axles have undergone rigorous testing to ensure compliance with Australian regulations. With second-stage manufacturing approval (VTA 061553), these portal axles are legal in all states of Australia, providing peace of mind for LandCruiser owners who are looking to enhance their vehicles' capabilities.
Expanded Payload Capacity
For 79 Series and 76 Series LandCruisers, the GVM (Gross Vehicle Mass) is increased from 3510kg to 3950kg with the installation of Marks 4WD Portal Axles. This expanded payload capacity allows for the transportation of heavier loads without compromising safety or performance.
Compatibility and Accessories
The Marks 4WD Portal Axles are designed to integrate seamlessly with the new GXL model of the 70 Series LandCruiser, equipped with factory diff locks, ABS, and ESC. The axles come as a standard kit that includes front and rear portal axle assemblies, forged chrome moly heavy-duty spindles, high-performance slotted brake rotors, ADR-approved stainless steel braided brake lines, and air-operated freewheeling hubs. Additional accessories such as Ironman Foam Cell Pro Shock Absorbers, Lovells/Terrain Tamer Coils, and Terrain Tamer Rear Leaf Springs ensure a well-rounded and optimized off-road setup.
