get in touch with us

6×6 vehicles are king of the off-road. This kit by Australian Expedition Vehicles & JMACX is utilised by extreme tourers around the world. They offer unmatched off-road capability, payload capacity and towing capability.

70 series and 200 series LandCruisers start out as capable four-wheel-drives when they roll off the dealer showroom, but combined with a 6×6 conversion, Boss Aluminium takes them to a whole new level. The system replaces the rear half of the chassis, integrating features such as heavy duty cable protection, integrated tow bar and rear winch cradle.
