The curtain will fall in 2026 on production of the Kenworth T800W and W900L, models that have served construction materials fleets for decades. The sunset is driven by evolving heavy-duty diesel truck emissions regulations and components constraints as the industry moves forward with new, more efficient, and better integrated technologies. Kenworth will announce a final call for T800W and W900L orders later this year—more than a decade after the debut of the models’ successor, the T880.
“We know these legacy models are an integral part of our history, which makes this decision a difficult but necessary one as we enter the next era of trucking,” says Kenworth Assistant General Manager for Sales and Marketing Kevin Haygood. “As we transition to future products, we remain committed to honoring the spirit of these iconic trucks by delivering innovation, efficiency, and the same level of craftsmanship that our customers and drivers have trusted for generations.”

Kenworth launched the T800 in 1986, promoting the series’ suitability for mixer, dump and other vocational applications. Built to accommodate large engines with increased cooling capacity and rugged components, the T800W has remained a favorite among heavy haul and off-road fleet operators.
Dating to 1963, the W900 is one of the most iconic models in North America’s trucking history, Kenworth officials contend. The truck is known for its classic long hood, conventional design, rugged durability, driver-focused comfort and style, plus a customizable platform made it a reliable choice for dump, and other vocational and on-highway applications. The W900S was designed for concrete mixer upfitting, while the W900A provided improved cooling for optimal engine operation, the W900B sported a cab update and additional cooling innovations, and the W900L brought a long-hood variation for performance and appearance.
