Chassis

Toyota Hilux HILOAD 6x6

The frame is a new design, which is extended by 1230 mm. Of which 230 mm is in front of the rear axles. The front cross-members are carried over from the original frame, to retain the VIN-number of the donor vehicle. This new frame is 10% heavier than the original Toyota frame.

The first batch of vehicle is homologated at a GVM of 5610 kg. Later vehicles have a GVM of 6500 kg.

Suspension and axles

The vehicle keeps the Toyota independent front suspension layout, using new components. This upgrade includes uprated towers (on the frame) and spindles. The rear suspension is a new design. Both the rear axles have air suspension with load-sensors to adjust the ride height. Hydraulic bump stops assist the air suspension when the vehicle drives off-road. The first batch of vehicles have uprated Toyota Hilux axles, later vehicles have custom axles.

6x6 drive

A second transfer case mounted behind the original one, which powers both the rear axles. Inside this transfer case sits a ‘Torsen-style’ differential with locking function. It means the differential in the second transfer case does have helical gears. Under normal driving conditions, it splits the power over the two rear axles. The locking function means the transfer case can lock itself when one of the rear axles loses all traction. This is not a standard feature of helical gears. Some implementations do have a locking mechanism. One of these sits in the transfer case.

The original transfer case drives the front axle via a selectable front wheel drive. The vehicle is still rear-wheel drive (6x4) on paved roads.

Misc

The front brakes have 6-piston callipers and uprated brake pads. The rear axles keep the stock brakes. All 3 axles have ABS brakes.
