Description
Offered here is a 2019 Kenworth T800 8x4 Tri-Axle Day Cab Truck Tractor, built for the most demanding vocational, bulk haul, and heavy-duty applications. This unit combines Kenworth’s legendary chassis durability and driver-focused ergonomics with the proven performance of the Cummins X15 450 HP engine, robust Eaton Fuller 18-speed transmission, and a heavy-spec axle configuration. Outfitted with essential vocational upgrades such as a wet kit, PTO, and blower, this truck is fully ready for work in industries ranging from construction and mining to pneumatic tank hauling, lowboy trailer operations, or municipal infrastructure.
At the heart of this T800 is the Cummins X15 engine, delivering 450 horsepower and a torque output rated up to 1,850 lb-ft. This is the 2017 EPA-certified version, ensuring emissions compliance via the integrated EGR, DPF, DOC, and SCR aftertreatment systems. The X15 is well known for its outstanding durability, long service intervals, and high torque at low RPMs—perfectly matched to demanding haul cycles.
Paired with the engine is an Eaton Fuller RTLO-18918B 18-speed manual transmission, offering superior gearing flexibility, exceptional hill-climbing ability, and precise control whether on the highway or in off-road conditions. This transmission is designed for high-GCWR operations and is widely regarded for its dependability and ease of maintenance.
With 4,280.9 verified engine hours, the drivetrain remains in its prime operating window. Regular maintenance has ensured optimal performance, and the truck is field-ready without the need for major component replacements.
This T800 features a durable 8x4 chassis layout with a 262-inch wheelbase, supporting both stability and maneuverability. The 13,200 lb front axle handles heavy steering loads with ease, while the 46,000 lb rear tandem axles—paired with an air lift pusher axle—allow for excellent weight distribution, increased legal payloads, and reduced wear when the pusher is lifted during unloaded runs.
The 8-bag air suspension system provides a smooth ride across varying terrain, and the double differential locks ensure traction in off-road or low-traction conditions. The pusher axle, which is air-liftable, allows the truck to legally carry heavier loads by spreading weight across additional axles while offering the option to lift it during light-duty or return trips, saving fuel and tires.
Aluminum wheels and 11R22.5 tires on both front and rear axles contribute to reduced unsprung weight and improved fuel economy, while maintaining durability and road grip under load.
