Western Star recently announced new options available on its 49X model that will widen coverage for heavy haul and construction applications.

The company has introduced an optional Power Hood for 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 moulded resin material as the sloped 49X hood, the Power Hood is designed for applications that require higher horsepower ratings, such as heavy haul, oil field service and construction.

The Power Hood is available with the Detroit DD16 engine, with up to 600 hp/2,050 lb-ft torque, or the Cummins X15 engine, offering up to 605 hp/2,050 lb-ft torque, and the 49X’s 1,600-square-inch radiator.

Also expanding the 49X’s heavy vocational application coverage is 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+ lb.

The Power Hood and P600 drive axle will begin production on the 49X starting September 2022.

Factory-installed twin steer front axle options are also available for order on the Western Star 49X and 47X trucks in set-back axle configurations. These twin steer configurations are designed for heavy construction applications, such as a concrete pumper, oil field service trucks, cranes, mixers, and more.

The 49X offers Detroit tandem front axle ratings of 40,000 and 36,000 lb., paired with equalized flat leaf front slippered suspensions. The 47X features a Detroit tandem front axle rating of 40,000 lb., paired with equalized taper leaf front suspensions. These twin steer options offer increased load capabilities on the front axles along with improved steering traction, weight distribution, and easier cab access compared to previous Western Star models.
