HOWO NX 6x4 Tractor Truck — Used Prime Mover for Export

What Is the HOWO NX Cab — and Why Does It Matter?

HOWO introduced the NX cab as a step up from the older A7 and T7 platforms, bringing a wider, taller sleeper space, better noise insulation, and a more driver-friendly dashboard layout. For long-haul operators running routes from Mombasa to Kampala, Durban to Johannesburg, or Jebel Ali to Baghdad, the extra comfort matters — rested drivers make fewer mistakes on difficult roads.

From a mechanical standpoint, the NX cab sits on the same proven SINOTRUK chassis architecture that fleets across Africa have run for over a decade. Engine mounts, cross-members, fifth-wheel height, and kingpin compatibility all carry over, which means local fabricators and trailer yards already understand how to work with it. That familiarity keeps downtime short when something needs attention. The NX tractor head is purpose-built for semi-trailer haulage. It does not carry payload itself — its job is to pull. Couple it to a container trailer, flatbed, lowbed, or curtainsider, and you have a freight unit capable of handling the bulk of B2B cargo moving through sub-Saharan Africa and the Gulf.

Engine and Drivetrain: WD615.47 371HP

The WD615.47 is a six-cylinder in-line turbocharged diesel displacing around 9.7 litres. At 371HP it sits in the sweet spot for GCW ratings common in African markets — typically 40 to 55 tonnes depending on the trailer and the axle configuration of the combination. Peak torque arrives low in the rev range, which is exactly what you want when pulling a loaded container trailer off a soft shoulder or climbing a gradient on the Zambia–DRC border road.

Paired to the HW19710 10-speed manual gearbox, the driver has enough ratio spread to keep the engine in its torque band whether crawling in traffic through Lagos or cruising a dual carriageway outside Dubai. The HW19710 is a known unit with straightforward synchromesh on the upper gears; independent gearbox repair shops across East Africa and West Africa stock its common wear parts.

The 6x4 axle configuration means two driven rear axles. On unpaved roads, loose gravel, or wet clay — conditions that are routine in Uganda, Ghana, and parts of Iraq — the spread of drive over four rear tyres gives meaningfully better traction than a 4x2 arrangement. When one axle breaks traction, the other continues to push. Fuel capacity sits at 400 litres, enough for roughly 1,000 km between fills under normal load and speed conditions.

What Can the HOWO NX 6x4 Pull? GCW and Trailer Pairing

As a prime mover, the HOWO NX 6x4 tractor is matched to a semi-trailer at the fifth wheel. Common combinations include:

• 20ft or 40ft container trailers — the most common use case for port-to-inland hauls out of Durban, Mombasa, Dar es Salaam, and Tema.
• Flatbed and drop-deck trailers — for construction materials, steel coil, machinery, and agricultural inputs.
• Lowbed trailers — for excavators, bulldozers, generators, and other oversized cargo. The 371HP engine handles these loads on reasonable gradients.
• Curtainsider and dry-van trailers — for consumer goods, bagged commodities, and FMCG distribution.

Typical GCW for a 6x4 HOWO tractor running on African roads is 40–55 tonnes, though local axle-load regulations vary. Buyers in South Africa work within the 56-tonne GCW limit on national roads; Nigerian buyers running interstate corridors often calculate around similar limits. We recommend confirming the legal GCW for your specific routes before finalising your trailer spec. If you are currently running tractor trucks from Isuzu, Hino, or Fuso and considering a switch, the main practical difference is parts cost and lead time. HOWO parts for the WD615 engine and HW gearbox are stocked by multiple suppliers in Nairobi, Lagos, Johannesburg, and Dubai — usually arriving faster and costing less than equivalent European or Japanese driveline components.

Refurbishment and Pre-Export Inspection

Every used HOWO NX 6x4 that leaves our yard goes through a documented inspection and refurbishment process. We are not a broker listing trucks we have never seen. The units are physically with us, and our workshop team checks each one before it is offered for sale.

What that process typically covers:

• Engine assessment — compression test, oil consumption check, turbo condition, coolant system integrity.
• Transmission and driveline — gearbox shift quality, clutch condition, propshaft and universal joints, differential oil seals.
• Brakes — service brake lining thickness, air system pressure hold, ABS (where fitted).
• Cab and electrics — instruments, lighting, wiring loom condition, cab mounts.
• Fifth wheel and kingpin coupling — jaw wear, locking mechanism, plate condition.
• Tyres — tread depth check on all 10 positions (12R22.5); replacements recommended or fitted where below minimum.

We provide a refurbishment report with the truck. If you or your agent want to inspect in person before payment, we welcome that — our yard is accessible and we do not object to third-party inspection. Units are priced as-is after refurbishment. We do not advertise prices online because condition, mileage, and specification vary between individual trucks.

LHD or RHD — Export Logistics and CIF Shipping

Traffic direction determines which drive side you need, and getting it wrong is an expensive mistake. We supply the HOWO NX 6x4 tractor in both configurations:

• Left-hand drive (LHD) — required for UAE, Iraq, and most of West Africa (Nigeria, Ghana, Senegal, Côte d'Ivoire).
• Right-hand drive (RHD) — required for South Africa, Kenya, Tanzania, Uganda, Zambia, Zimbabwe, and most of Southern and Eastern Africa.

Confirm your country's traffic side before enquiring. If you are unsure, tell us the destination port and we will confirm. We ship CIF (Cost, Insurance, Freight) to approximately 40 destination ports, including Durban, Mombasa, Dar es Salaam, Tema, Apapa (Lagos), Jebel Ali, Umm Qasr, and others. CIF means the truck is loaded, insured at sea, and delivered to the named port — you handle import clearance and onward movement from the port. We prepare the Bill of Lading, commercial invoice, packing list, and any origin documentation required by your customs authority. Typical transit times from China to East Africa are 18–28 days by sea; West Africa 22–35 days; Middle East 12–20 days.

Parts Availability and Long-Term Running Costs

One of the most common questions we hear from buyers comparing the HOWO truck range against Japanese or European alternatives is about parts. For the WD615.47 engine and HW19710 gearbox, the answer across most of our markets is that they are available — and at a lower cost per part than equivalent components for Isuzu, Hino, or Mercedes-Benz. Here is why:

• Volume: HOWO is one of the highest-volume heavy truck brands operating across sub-Saharan Africa. High volume means parts dealers stock the fast-movers as a matter of course.
• Supplier network: Chinese parts manufacturers export through distributors in Nairobi, Lagos, Johannesburg, and Dubai. Lead times for most serviceable items are days to weeks, not months.
• Commonality: The WD615 engine family has been in production for many years. Pistons, liners, injectors, head gaskets, and turbo cartridges for this engine are not exotic items.

That said, parts availability varies by city. If you are operating in a smaller inland town with limited truck spare parts trade, it is worth mapping your nearest HOWO parts supplier before committing to any truck purchase. The howo 371 HP specification — which this truck carries — has been widely established in African fleets for long enough that many local mechanics are familiar with the engine at a practical, hands-on level.
