Refurbished HOWO NX 371HP 6x4 Tractor Truck
This page describes a representative HOWO NX 371HP 6x4 tractor configuration. Because refurbished trucks vary by production year and previous use, the quotation should identify the exact VIN/chassis number, mileage, engine number, cab, fifth wheel, tires and completed refurbishment work.
Before payment, request current-unit photos, a cold-start and walk-around video, fifth-wheel and chassis close-ups, and either a live video inspection or an independent inspection.

Refurbished HOWO NX 371HP 6x4 Tractor Truck FAQ
Is every tractor on this page the same specification?
No. Production year, cab, wheelbase, axle ratio, fifth wheel, tires, tank and condition can vary. The signed vehicle-specific quotation and VIN/model plate define the supplied unit.
How can I confirm it is a HOWO NX rather than another HOWO series?
Request clear photos of the complete truck, VIN/chassis plate, cab identification and engine plate. Match them to the quotation before payment.
What current-unit evidence can I request?
Request dated exterior and interior photos, plate close-ups, mileage, cold-start and walk-around video, chassis and fifth-wheel close-ups, tire condition and a live or independent inspection.
What is the price?
Price depends on the exact production year, mileage, condition, configuration, refurbishment scope, destination and shipping method. Ask for a quotation tied to a specific VIN or stock number.
What is the minimum order quantity?
Order quantity must be confirmed in the current quotation. A single-unit inquiry can be submitted for availability and shipping evaluation.
How long is preparation and delivery?
Timing depends on current stock, the agreed refurbishment scope, inspection, export documents, port schedule and destination. Request a dated preparation and shipping estimate for the selected unit.
What warranty is included?
Warranty coverage is not assumed from this page. Ask for the written warranty terms, covered components, duration, exclusions and claim process in the vehicle-specific quotation.
How do I confirm fifth-wheel compatibility?
Provide the trailer kingpin size and required coupling height. Confirm whether the tractor has a 2-inch or 3.5-inch fifth wheel, then verify mounting height, wear and locking operation on the exact unit.
Request a Vehicle-Specific Quotation
Send your destination country, intended trailer or load, required fifth-wheel size, preferred production year and any inspection requirements. The quotation should identify the exact available tractor and the evidence supplied with it.
