(Photos credit: Kenworth Trucks) – When it comes to big, awesome trucks there are few bigger and more awesome than the mighty Kenworth 963 oil field truck. These massive off-highway trucks spend their time working in the desert or other inhospitable places where oil rigs are present. Their primary job in the field is to help move heavy equipment and drilling rigs. The truck you’ll see coming together below is a cab and chassis. It is most likely heading to an upfitter so that a huge oil field body can be mounted to it with winches, potentially a lifting arm, and other appendages so that it can complete its designated work.

If you are wondering about the massive tires that look they’ve come off of an airplane, they are flotation tires that are designed to work best on loose sand to keep the truck from sinking into an ancient Pharaoh’s basement or something to that effect. As you’ll see in the photos, these are 6×6 trucks with the front axle also being powered along with the rear two. Seeing the photos of this truck on a lowboy trailer and completely dwarfing the KW rig that is hooked to the trailer.

Kenworth recently published some fun facts about the 963. Here’s what they said:

Note a couple of things there. The gross combo weight on this thing, meaning the truck with a trailer or payload is 500,000lbs. Yeah, half a frigging million pounds! Also note that the rear axles have a 150,000lb capacity each and the gear ratio is 15.03:1 — Even in 6th gear we bet this truck isn’t going to hit 40mph!
