Today, you need equipment that’s easier to own and more affordable to operate. Equipment that will work harder, last longer and retain its value. Today, you need a more productive, more. Kenworth’s T800 is the ultimate workhorse – as much at home running freight coast to coast as it is delivering fuel across town or hauling gravel out of a quarry. Imagine the bottom-line advantages of a single base chassis that can do almost anything you ask of it. Plus, the T800 is built-to-take-it tough – proven very, very difficult to break.

T800 Description
Kenworth T800 Under the Hood

• The T800, with its 48.5-inch set-back front axle, enables you to transfer more of the vehicle’s weight to the front end – taking full advantage of its rated capacity. Any weight you can legally shift to the front axle, you can profitably add to payload – each and every truckload. More Agility: The T800 incorporates advanced steering geometry that produces maximum wheel cut and a tight turning circle – even with flotation-type tires and front drive axle configurations. That advantage, plus a dramatically sloped hood and strategically placed, generously sized windows can increase driver confidence in tight situations. 

• Inside, the T800 is pure Kenworth – ergonomically designed and filled with more driver-pleasing space, convenience features and luxury detail than you’ve ever imagined in a truck this productive.
