2026 Western Star 47x

Application fitment centers on vocational dump duty with low miles and a new-condition baseline, suited to short-cycle work where stop, start, and PTO-adjacent operation are common. Chassis configuration shows a Class 8 tandem 6x4 with spring suspension and a 218-inch wheelbase, a layout that favors stability under load and predictable roll control over ride softness. Powertrain pairing uses a Detroit DD13 rated at 470 hp tied to an Allison RDS 6-speed automatic, a combination that prioritizes consistent launch behavior, controlled low-speed maneuvering, and reduced shift workload in traffic and on job sites. Driveline spec details beyond that are not provided, so axle ratio and locking strategy should be confirmed if the work includes sustained highway runs or soft-ground starts. Frame and running gear present as steel construction with aluminum wheels, tandem drive, and spring packs, points to inspect early are spring eye bushings, U-bolt torque witness marks, and any paint rub at hangers that would indicate settling after initial service. Cab layout is left-hand drive, and with only 1,500 miles the practical checks are baseline items, fluid levels, air system build time, and any early seepage at charge-air connections and coolant joints that can show up after first heat cycles.
