Up for sale is a well-maintained and extensively refreshed 2009 Kenworth W900B flattop, ready to go straight to work. This is a clean, solid truck with extensive upgrades and mechanically sorted, tastefully improved, and personally owned, not a fleet vehicle.
This truck has had major drivetrain work completed around 400K miles, including a full in-frame overhaul and transmission replacement, making it a strong, reliable platform for years to come. Since then, it has been lightly used and carefully maintained.
The truck is currently set up at ~600 HP, runs strong, and has no known mechanical issues.
Whether you're looking for a dependable work truck or a clean owner-operator setup, this W900 checks all the boxes. I am only selling this truck to make room for a new Kenworth that is currently on order.
