Kratos was designed from the ground up to stand out from the rest and perform flawlessly where needed. Based on a new 3-ton chassis, this heavy-duty jack has solid axles and large non-pneumatic wheels to give it lift. You will no longer have to worry about dragging your cat through sand or not being able to run over a zip tie or pebbles in the garage. We worked hard to create the ultimate Off-Road Jack that would hold up to the toughest off-road racing conditions. Please note that this is not a bolt-on wheel kit. This jack does not have standard wheels and cannot be converted to a standard jack. It is built in our factory like a big wheeled monster. Specifications High capacity, non-pneumatic, composite wheels Sealed ball bearings on all 4 wheels Solid steel axles All aluminum construction 60lbs Cover included
