The HOWO NX 371 keeps the 371 hp WD615.47 drivetrain of the classic HOWO 371 and puts it in SINOTRUK's newer NX cab. Buyers in Kenya and Tanzania often ask for it by name as a prime mover for container and long-distance work.
Our NX spec sheet lists the HW19710 10-speed gearbox, MCX16ZG rear axles with a 4.803 ratio, a 600 L fuel tank and a 50# fifth wheel. The main step up is the cab: heating and air conditioning, an air-suspended driver seat and the NX interior.

Condition and warranty
- Brand new: factory order to the specification above
- Refurbished NX units: quoted when available, with the work done listed on the quotation
On new and refurbished trucks, the engine, gearbox and rear axle carry a 12-month warranty; wear parts are not covered. Your quotation states the condition, the work done and the parts replaced.
Before the balance payment, ask for dated photos and a video call of the actual truck: chassis, cab, engine bay, gearbox, axles, tyres and odometer. Independent inspection by SGS, Bureau Veritas or another inspector is welcome.
Export documents and shipping
We supply the commercial invoice, packing list, bill of lading and Certificate of Origin. Destination inspection and conformity documents depend on your country: check steering side, emission standard, vehicle age limits, duties and registration rules with a licensed clearing agent before ordering.
Delivery to a Chinese port takes 30 to 45 working days after the deposit. Trucks normally ship by RoRo, or by flat-rack where RoRo is not available. Prices are EXW Jining; sea freight is quoted separately when the truck is ready to ship.

Frequently asked questions
How much is a HOWO NX 371 tractor head?
Price on request: the NX is quoted by configuration and condition. Send your quantity, destination port and drive side, and we reply with an EXW Jining price, usually within one business day.
Does the HOWO NX 371 have air conditioning?
Yes. The NX cab on our spec sheet has air conditioning with heating and cooling, an air-suspended driver seat and a sleeper.
Which is better for me: HOWO 371, NX or TX?
The 371 and NX share the same 371 hp drivetrain; the NX has the better cab. The TX is a higher-power truck for heavier loads and hills. Our guide on HOWO 371 vs NX vs TX compares them in detail.
Can I get the HOWO NX in right-hand drive?
Yes, left- and right-hand drive are both available. The drive side is confirmed on the proforma invoice before you pay a deposit.
Can I get the exact truck specification before payment?
Yes. Ask for the chassis model, engine, gearbox, axles, wheelbase, tyres, body or equipment, condition, price, Incoterm, and delivery schedule in the quotation and proforma invoice. Do not rely only on a general catalogue description.
Can an independent company inspect the truck?
Yes. Independent pre-shipment inspection is welcome. The inspection scope should compare the actual truck with the signed specification and record identification plates, condition, operation, dimensions, and visible defects.
Is the displayed specification guaranteed for every unit?
No. It describes common configurations. Stock and factory-order specifications can vary. Only the final written sales documents and inspection record define the truck being supplied.
