Introduced in 1961, the W900 (the 'W' honors Kenworth co-founder Edgar Worthington) defined the long-hood American conventional and pioneered bulkhead-style doors with full-length hinges that rivals later copied. The 1990 W900L added 10 inches of hood, and after a 63-year run Kenworth confirmed in 2025 that the legendary truck would end production in 2026.
