The Western Star 49X has been engineered from the ground up. The longer hood and 121.5" BBC make it the ideal choice for heavy-duty applications, delivering power, durability, and technology for any job that needs to be done.
Able to be fit with the Detroit® DD16®, the industry’s only 16-liter engine, delivering up to 600 HP and 2,050 lb.-ft, the 49X is built to make the most daunting hauls look and feel easy…again and again.
The 49X features a heavy-duty frame, engineered and built from the ground up to meet the demands of severe applications while still being lighter weight, durable, and easy to service.
However far off road you go, break new ground in power and maneuverability.
The 49X weighs in as the heavy haul champion, built to move over a half million pounds with ease.
From Arctic ice roads to sweltering Texas oil fields, THIS IS where comfort meets confidence.
The 49X gives you a choice of cab configurations to best support the application of the tractor and enhance the productivity of the operator. The cab will determine the length of the chassis, the height of the vehicle, and the electronic controls on the back of the cab.
Short sleepers (36” and 48”) are designed for a comfortable environment to grab a short rest in vocational tractor applications. Larger sleepers (60” and 72”) deliver the comforts of home.
The 49X interior features all the comforts that make the long days a little bit easier. The spaciousness creates an inviting environment while the insulation, fit, and finish improve both sound levels and temperature control. And the ergonomic design puts control and critical information within reach, making every job more manageable. It’s the kind of comfort that keeps your operators alert and helps keep your business profitable.
Built for operators who need serious pulling power, the optional Power Hood on the Western Star 49X is purpose-built to support larger radiator packaging for high-output engines, including DD15 and DD16. By accommodating the increased cooling demands of applications that require the highest gross combined weight limits, it delivers the performance needed for heavy-haul, oil field, and severe-duty use cases—while maintaining the classic Western Star hood design.
The X-Series tractor is engineered to handle extreme loads and deliver greater uptime for improved profitability. Add the optional Power Hood to accommodate higher horsepower engines.
The 49X is infinitely configurable in its customizable switches, as well as clear BOC options with fuel tank sizes ranging from 60 to 100 gallons.
Detroit’s integrated powertrain solutions give your 49X tractor even more ways to deliver high horsepower, torque, and pulling power for heavy trailers. Heavy-duty engines, transmissions, and axles are designed to work together seamlessly for reliability in handling extreme loads and challenging vocational hauling conditions.
