Perfect for tanker applications, the Kenworth T800 can be specified with a long list of weight-saving components without compromising reliability. For hauling high center of gravity loads, a strong, stable frame is a must. The Kenworth T800 offers a variety of frame sizes and inserts (double frame) designed to meet the most demanding requirements. Maybe you need a truck with some serious backbone. Dump truck. Mixer. Lowboy. Logger. Kenworth knows how to build trucks that can shoulder maximum payload with minimum tare weight and move that burden with sure-footed confidence over steep, uneven and slippery job sites. That’s why the Kenworth T800 starts as a clean sheet of paper, its wheelbase custom tailored to your specifications. Your design choices encompass the latest technologies and a spectrum of proven heavy-duty components for GCWs to 330,000 pounds. The highest horsepower engines. Radiators are sized from 1,440 to 1,780 square inches. Front axles up to22,000 pounds. Twin steer front axles to 37,500 pounds. Front drive axles. Pusher axles and tags.

It has one of the tightest turning radiuses of any truck and offers many weight-saving options to help boost usable payload. DayLite doors and a one-piece windshield improve visibility. The Kenworth T800 is the truck of choice for tough logging operations. Available in several hood options, a wide-hood T800 combines traditional good looks with the excellent maneuverability of a set-back front axle. When it comes to pulling the biggest, heaviest loads, you want a Kenworth. The Kenworth T800 offers a 1,780 square-inch radiator to cool the highest horsepower engines - even under the most demanding conditions.Lift axles can be factory-installed providing a fully integrated solution where the braking system, lift controls/piping, frame and even chassis components have all been designed with your final use in mind. Perfect for snowplows, municipal dump trucks, mixers, refuse trucks, and crane trucks that require front engine power take-off (PEPTO), the optional Kenworth factory-installed PEPTO avoids aftermarket retrofit problems. The 1,440 square-inch radiator includes a modified bottom tank for PTO shaft clearance. A front-frame extension provides space for front-mounted equipment like hydraulic rams or hose reels.More Payload: The Kenworth 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. More Control: Kenworth applies sophisticated ergonomic principles and state-of-the-art technologies to create trucks that are easier and safer to drive. Multi-function steering wheel, clutchless automated and automatic transmissions, multiplexed instrumentation and wireless communication systems all contribute to less fatiguing, more productive operation.The Kenworth T800 set-back axle, together with steering geometry that delivers up to 54 degrees of wheel cut - helps drivers optimize and maneuver loads with ease. A sloped hood gives the driver a much better view, offering more in-front-of-the-truck visibility than straight-hood conventionals. Optional cab-corner windows help drivers who need to see better in reverse, at intersections and around the job site. Kenworth’s multi-function Drive Performance Center provides the driver with important real-time information on truck performance. The touch of a button displays up-to-the-second readouts on cumulative trip fuel economy, optimum RPM for maximizing fuel efficiency, and system diagnostics. Comprehensive truck specification data - unique to the vehicle - is also available to speed troubleshooting and parts replacement. From day one, Kenworth has engineered strong, lightweight trucks you can count on. Trucks with an unmatched ability to stay together, do the job, cost less to maintain and pay back their investments. Just slam the door on a 10-year-old Kenworth mixer to see what we mean. Chances are it feels as solid as the day the truck left the factory. Legendary for its longevity and integrity, Kenworth’s conventional cab combines aluminum and fiberglass in a Huckbolted assembly that’s practically corrosion-proof and rattle-free. Then there are all the little things you might not notice that help keep big things from going wrong. Wiring and plumbing bundled together and mounted high in the frame, safe from chafing, road salts or washing acids. Rubber-bushed shackle pins and bushings to extend suspension life and improve steering. Constant torque hose clamps. Radiator tie rods mounted to the frame – not the cab – for longer radiator life. And so much more. It’s this kind of attention to detail that keeps you moving ahead. Day in, day out.Tip the hood to see what we mean (inner fenders tilt out of the way at the same time). The engine sits high in the frame and totally ahead of the cab for complete access. You can check fluid levels and change fuel, oil and water filters while standing on the ground – not on a tire. The heater/air conditioner motor, electrical master connectors, windshield wiper motor and washer reservoir are all on the firewall, making them easier to repair. Now take a close look at the engine cooling system. On a T800, it incorporates straight sections of reinforced rubber hose that are more readily available and much less expensive to replace than preformed hoses, along with steel elbows that are good for a lifetime of service. Even the electrical system – a maintenance headache for most operators – has been designed for durability and streamlined troubleshooting. Multiplex instrumentation greatly simplifies cab wiring, which is further color-coded and numbered for easy circuit tracing. Quick-to-fix engineering features like these can mean a lot less downtime, shop time and money out of your pocket.Whether you choose a workhorse-rugged, yet way-above standard Splendor interior or the custom look of a Diamond upholstery package, the inside of a Kenworth has been designed to help those behind the wheel operate at their absolute best. Perform at peak efficiency. And rest in an environment that brings them closer to home. Tour a Kenworth Studio Sleeper, or one of our AeroCab sleepers. Note the consummate balance between business and pleasure. The thoughtful, convenient and productive layout. The creative and elegant interior appointments. All handcrafted to the same exacting standard we use to build the rest of your Kenworth T800. Then imagine the pride you’d feel knowing you’ve been given the keys to The World’s Best truck. That sense of pride is one of the reasons Kenworth trucks last longer, work harder and bring more at trade-in. And one of the reasons Kenworth operators keep their best drivers.The result is an integrated, fully-engineered, job-ready solution you can depend on – right from the start. For hauling maximum legal loads without sacrificing strength and durability, you can select from a long list of weight-saving components and options including aluminum hubs, lightweight drums, aluminum clutch housing, aluminum bumper, lightweight charging/starting systems, composite leaf springs and more.As a custom truck builder, Kenworth offers more job-specific and factory-installed options than any other manufacturer. The extended day cab offers more head, leg and belly room than a standard Kenworth T800 day cab, plus extra storage space and reclinable seating - all with just a slight increase in tare weight. A DEF tank under the cab allows the Kenworth T800 to be configured so it will have a completely clear back-of-cab for a cleaner and easier body installation. A heavy-duty cast center tow hook provides a robust attachment point for severe service applications. Kenworth offers cowl-mounted stainless steel air cleaners from Donaldson. A new cowl design provides greater specification flexibility - offering flat and curved glass windshields with extended day cab and AeroCab sleeper options.
