MTM Heavy Haul & Earthwork Fleet
Western Star 47X Dump Trucks
MTM's 2025 Western Star 47X dump trucks bring serious hauling capacity to the field, built to move aggregate, excavation spoils, rock, and construction materials through demanding conditions. With a quad-axle configuration, 475 horsepower, an Allison 4500 RDS automatic transmission, and an 83,760-pound GVWR, these trucks keep material moving from the first load to the last.
Built to Haul
Designed for the field
The 47X is Western Star's vocational platform, designed around the realities of construction, quarry, and heavy-duty hauling. It is purpose-built for jobsite work—not a highway tractor waiting for a job.
Heavy-Duty Chassis
The vocational chassis is engineered for demanding dump-truck, concrete-mixer, and crane applications while keeping weight under control for payload capacity.
Cummins X12 Power
A 475 HP Cummins X12 delivers the power needed for loaded hauls, steep grades, and demanding site conditions.
Allison 4500 RDS
The automatic transmission puts power to work while simplifying operation in the stop-and-go conditions of construction and earthwork.
Quad-Axle Configuration
An 18,000-lb front axle, 46,000-lb rear axles, and two lift axles are configured for serious payload and tough jobsites.
