Western Star is adding new options to expand the capability of its 49X model truck to handle heavy haul and construction applications.
A new, optional Power Hood is being offered on the 49X, designed to allow for higher horsepower and more cooling for set-forward front axle configurations. Made from the same impact-resistant, durable, lightweight molded resin material as the sloped 49X hood, the new offering works well in applications that need higher horsepower ratings, such as heavy haul, construction and oil field service.
It is available with the Detroit DD16 engine, which offers up to 600 hp and 2,050 lb.-ft. of torque, or the Cummins X-15, at up to 605 hp and 2,050 lb.-ft. of torque, along with the 49X's 1,600-square-inch radiator.
A second new option is the availability of the Meritor P600 planetary drive axle. Available in tandem or tridem rear axle configurations, and paired with the Neway AD260 or AD390 rear suspensions, the P600 is designed for heavy haul applications with GCWs of 200,000 pounds and more.
"The 49X already is the most advanced vocational truck on the market. These new features make it more powerful and versatile so it can deliver even better performance and results for customers," said Mary Aufdemberg, General Manager, Product Strategy and Market Development, Daimler Truck North America. "Western Star loyalists will appreciate how the more traditional design of the Power Hood evokes the brand's storied heritage."
Both of these new options will be available on the 49X starting in September 2022.
Available now on both the 49X and 47X are factory-installed twin steer front axle options, available in set-back axle configurations. These twin steer configurations are designed for heavy construction work - such as concrete pumpers, cranes, mixers and others.
On the 49X, Detroit tandem front axle ratings of 40,000 and 36,000 pounds are available, paired with equalized flat leaf front slippered suspensions. The 47X features a Detroit tandem front axle rating of 40,000 pounds, paired with equalized taper leaf front suspensions.
These twin steer options offer increased load capability on the front axles, along with improved steering traction, weight distribution, and easier cab access compared to previous models.
"These new options for the X-Series are simply the latest results of Western Star's commitment to building the finest trucks for heavy haul, construction and other severe service applications," said Aufdemberg.
In addition to these factory-installed, set-back axle twin steer options, the 47X offers a twin steer prep kit for set-forward configurations. Factory twin steer production begins in late 2022 for the 49X and early 2023 for the 47X.
