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.


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.




Engineered For Long Life And Quick Upfit

The heavy-duty vocational frame underneath the 47X is engineered to stand up to the demands dump trucks, concrete mixers and crane trucks experience.

Powertrains You Can Count On. Every Single Day.

Whether your 47X is going to be working on construction sites, in quarries, in concrete plants — or even over the road — the DD13 delivers you the proven power.

Engineered For Upfit

The X-Series was created with Truck Equipment Manufacturers (TEMs) in mind. We designed the truck to ease body upfit for every type of truck including dump trucks, cement mixers, cranes, and engineered it with features to make it fast and simple to access wiring and add controls.

The X-Series Door

Built from rugged steel and designed to be easy to service, it will deliver greater uptime and operator comfort for years to come.


Trench-style Low Roof

Composite roof with a lowered center section enables optimized packaging of overcab equipment, giving you a purpose-built vehicle that minimizes overall vehicle height while maximizing interior headroom and door opening.


Our Job Is To Keep You Doing Yours

Our X-Series trucks represent a big advancement in productivity for vocational trucks thanks to Detroit Connect®. Detroit Connect translates the performance data of any type of truck into real-time information you can use to make the decisions that can help you keep those trucks working and earning.



Setting the vocational standard for safety and technology.

Leading the industry in vocational truck safety

The 47X is setting the vocational standard for safety and technology.

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.

Detroit Assurance
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.

* with DT12 Transmission

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

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

A windshield that makes it easy to see everything, including an advantage in safety
  1. Field of Vision - Delivers best-in-class field of vision thanks to a surface area that's 28% larger than our previous product offering, making it one of the largest windshields in its class.
  2. One-Piece Design - Roped-in design for easy removal and replacement in case of damage.
  3. Solar Film - Optional solar film reduces heat in the cab, improving operator comfort.
  4. Wider Wiper Zone - 24-inch wiper blades that cross over the center of the glass for a 37% improved wiper zone, giving operators a wider range of visibility and better unobstructed view.
Dual Stage Intelligent LED Headlights
  1. Impact Resistance - High-impact polycarbonate lenses with additional hard coating protection to prevent cracking, scratching or damage to the headlight from road or jobsite debris.
  2. Heated Lens - Dual Stage intelligent heat grids to melt away ice and in humid environments, eliminate condensation, in minutes.
  3. Integrated Amber DRL - Integrated amber daytime running lights that double as turn signals, making the truck more visible to oncoming traffic and on the jobsite.
  4. Wide Illumination - LED output is designed to fully illuminate the road and jobsite, including off to the sides of the vehicle, to reduce eye fatigue while letting operators detect objects sooner.
