Expanding the already impressive line of next gen vocational trucks.

Western Star 47X Truck Side View


Our X-Series trucks aren’t just the best trucks we’ve ever built, they’re the best trucks anyone has ever built.

Like the 49X before it, the 47X is part of a family that was built from the ground up to bring toughness into the modern age with an impressive collection of engineering, technology and more than half a century of experience building trucks that take on any challenge, anywhere.


Even more vocational applications

The 47X extends the reach of the X-Series into even more vocational applications, with a number of new features including a shorter hood and a shorter 111" BBC. This shorter configuration is ideal for applications that require optimized equipment packaging to meet local overall vehicle length requirements and applications that need to adhere to bridge laws, such as concrete mixers or dump trucks. So, no matter what job you need to do, there’s now another purpose-built tool to do it. Break new ground with the 47X.

Western Star 47X Features


Introducing Detroit Assurance

Technology gets tough in the X-Series, the first Western Star trucks to feature the most advanced suite of active safety systems ever offered to the vocational market — Detroit Assurance. Detroit Assurance not only helps keep people safe, it helps you reduce the repair and operational costs of having a truck out of service by avoiding collisions — which can mean game-changing productivity to you.

Active Brake Assist 5

Active Brake Assist 5 detects distance and speed to moving and stationary objects in its path and determines if warning or braking is necessary. It's the only system on the market that works down to 5 MPH*, making it ideal for travel in congested urban areas. It also recognizes pedestrians who are about to cross in the truck's path, alerting the operator while partially braking, followed by full braking if the operator does not react.

Side Guard Assist

A game changer for safety in and around busy jobsites, Side Guard Assist detects objects on the passenger side of the truck and alerts the operator.

Adaptive Cruise Control To 0 MPH And Tailgate Warning

Detroit Assurance technology enables state-of-the-art features such as Adaptive Cruise Control to 0 MPH* and Tailgate Warning to ease driving in stop and go traffic, as well as help reduce collisions as operators travel from one jobsite to the next.

* with DT12 Transmission

Brake Hold Mode

Available in 2022, Brake Hold Mode enhances driver safety and comfort on the road and at the jobsite. This state-of-the-art feature keeps a truck* stopped when the driver removes their foot from the brake pedal, or if their foot unintentionally slips off.

* with DT12 Transmission

Interior options and features

Tough on the outside. Very comfortable on the inside.

The 47X Dash Features

The dash of 47X is a study in forward-thinking engineering and design, with every decision made to let operators keep their hands on the wheel and eyes on the road.
