T800

The legendary do-anything workhorse.

Introduced in 1986 and nicknamed the 'Ultimate Workhorse,' the T800 became Kenworth's go-to vocational truck for dump, logging, tanker, and heavy-haul duty, with the wide-hood T800W rated to carry a Gross Combination Weight up to 330,000 lbs. After nearly four decades it was sunset alongside the W900 and C500, with production ending in 2026 over EPA emissions and component constraints.
