2026 Western Star 47X

Category, Truck (dump application), Class 8 tandem, 6x4, steel spec. Low-mileage use at 1,000 miles points to early-life shakeout rather than a full duty-cycle history, so the practical value here is getting a dump chassis with minimal wear on driveline, suspension pins, and body hardware. Powertrain, Detroit DD13 rated at 470 hp paired with an Allison RDS 6-speed automatic. Automatic control suits stop-and-go dump cycles, tight jobsite maneuvering, and consistent launch with varying payload, spring suspension and tandem drive keep the setup straightforward for on and off pavement work. Wheelbase at 218 inches reads as a balanced dump layout, not stretched for long haul. Frame rails, steel construction with tandem spring suspension means fewer air system components to maintain, but it puts more attention on spring packs, U-bolts, equalizers, and torque rod bushings as the miles accumulate. Wheels, aluminum, reduce unsprung weight and corrosion concerns around rim flanges, check for jobsite rash and lug seat condition during walkaround. Cab layout, left-hand drive, keep an eye on interior switchgear and PTO, hoist controls if fitted, since no body or hydraulic specs are provided here.
