Portal hubs feature on many high ground clearance military-type machines, including the Mercedes-Benz Unimog. You can have these fitted to your LandCruiser ute, but they’re not cheap.
A locally engineered portal axle kit forthe Toyota Model VDJ79 single and dual cab LandCruiser is possibly the ultimate lift kit, providing 150mm (six inch) legal lift under the axle.
Portal hubs are also known as ‘drop boxes’ that use gears inside their hubs to move the wheel centre lines below the axle centre lines.
Designed and manufactured by Mark’s 4WD Adaptors, the new axle provides greater clearance under both axles and corrects the track width of the rear axle to match the front. wheels and increases the gross vehicle mass to 3780kg.
