Kenworth T8 Series – register collective name for T800 and T880 by PACCAR in Kirkland, Washington: six- to eight-cylinder engines, 10,837 to 12,900 cm³, gross weight up to 27.9 tonnes
Kenworth, founded in 1923 in Seattle and now headquartered in Kirkland, Washington, as a brand of PACCAR, combines the heavy T800 and T880 ranges in the register under the name T8 Series. The T800 has been built since 1986 as a versatile chassis for long-haul, construction and heavy-duty use, while the T880 has complemented it since 2013 as a successor for construction and mixer applications, with a shorter bonnet and a larger turning circle, which eases manoeuvring on construction sites.

The register lists here 6 versions with displacement from 10,837 to 12,900 cm³ from six- to eight-cylinder engines, unladen weights from 7,475 to 12,860 kg, gross vehicle weights from 18,600 to 27,900 kg, lengths from 7,530 to 11,200 mm and widths from 2,500 to 2,550 mm.
The T800 and T880 are among the common chassis in North America for concrete mixers, dump trucks, lowboy trailers and long-haul tractors, competing there with Peterbilt, Freightliner and Mack.
When buying used, key points are mileage and service history of the engine and transmission, the condition of the frame and body mounts in construction and mixer use, the axles and brake system under heavy load, and corrosion on the cab; spare parts are supplied through the Kenworth and PACCAR dealer network, which covers all of North America.
