This brand-new 2026 HOWO TX 6x4 tractor is a factory right-hand-drive (RHD) truck specified for long-haul logistics and container transport in East Africa, Southern Africa and Southeast Asia. It combines the urea-free SINOTRUK WD615.47 371 HP Euro II engine with the HW19710 10-speed transmission, a German MAN TGA technology chassis, MCJ12BGY tandem rear axles at a 3.70 ratio and a 600 L aluminium fuel tank. Model code ZZ4257N324GB1R. Contact HiCA AUTO for FOB or CIF pricing.

Factory Right-Hand Drive — Built on the Line, Not Converted Locally

The first question every RHD buyer asks is whether the truck left the factory as a right-hand-drive vehicle or was cut over from left-hand drive afterwards. This ZZ4257N324GB1R is a genuine factory RHD unit from SINOTRUK's TX series: the steering gear, instrument panel, wiring harness and pedal layout are integrated during assembly, so there is no aftermarket steering box, no spliced electrical loom and no re-routed brake or clutch plumbing waiting to fail in service.

That difference matters on a working truck. Converted cabs are where electrical faults, steering play and permanent dashboard warnings usually originate, and they are the first thing an importer's inspection looks for. Because this is an original TX-F RHD cab, this HOWO TX tractor truck arrives with one consistent wiring standard, vehicle documentation that matches the unit, and parts that can be ordered by model code rather than by guesswork.

For operators running mixed fleets, an authentic RHD tractor truck also means one service procedure, one spare-parts list and one driver-training standard across every unit in the yard.

WD615.47 371 HP Euro II Engine — No Urea, Tolerant of High-Sulphur Diesel

The WD615.47 is a 371 HP inline-six, four-stroke, water-cooled, turbocharged and intercooled diesel engine. It uses a purely mechanical injection pump and meets Euro II emissions, which is exactly why it remains the default specification across right-hand-drive markets: there is no SCR system, no DEF/AdBlue tank and no urea dosing to refill, freeze, crystallise or fail on the road.

In daily operation this removes an entire maintenance stream. Mechanical injection tolerates the higher-sulphur diesel that is common outside Europe, and there is no emissions sensor able to derate the engine or send the tractor truck into limp mode hundreds of kilometres from the nearest workshop. A 71 °C thermostat is specified for hot operating conditions, and an optional Parker coarse fuel filter with water separator can be fitted to protect the injection system further in dusty or inconsistent-fuel environments.

An EVB exhaust valve brake is fitted as standard. On long descents it adds usable retarding force, reduces service-brake and drum wear, and makes a fully loaded HOWO TX 6x4 tractor truck noticeably safer to bring down a mountain grade.

HW19710 10-Speed Twin-Countershaft Transmission

In this HOWO tractor truck, power reaches the wheels through the HW19710 manual gearbox with 10 forward gears and 2 reverse gears. Its twin-countershaft design splits torque across two intermediate shafts, which is why this transmission survives the heavy start-stop duty that destroys single-countershaft units: the shock load of a loaded hill start is distributed across two gear trains instead of being concentrated on one set of teeth.

Gear steps are spaced for strong loaded pull-away and relaxed highway cruising, so the driver is not constantly hunting for a gear on a climb. Synchromesh life is long and shift feel remains positive, which matters on the multi-day line-haul work this tractor truck is specified for, where driver fatigue translates directly into fuel consumption and risk.

The two reverse ratios are more useful than they sound. The shorter reverse gives precise low-speed control when positioning a trailer in a tight port yard or a crowded logistics park, while the longer reverse covers extended reversing distances without over-revving the engine. The result is a driveline that is uncomplicated to operate and inexpensive to keep running.

MAN TGA Technology Chassis and MCJ12BGY 3.70 Rear Axles

The chassis of this HOWO tractor truck is built on German MAN TGA technology: a high-strength steel frame engineered for bending and torsional stiffness, so the rails hold their geometry under sustained heavy loads and rough-road use rather than deforming over time. Front axle is the VGD71 rated at 7.5 T with drum brakes; the rear is an MCJ12BGY MAN-technology single-reduction tandem set, also on drum brakes, with a 3.70 final drive ratio quoted at over 98 % transmission efficiency.

That 3.70 ratio is a highway ratio, and it is the reason this RHD tractor truck is specified for long-haul rather than site work. At cruising speed the engine turns lower rpm for the same road speed, which cuts fuel burn and engine wear on long intercity and cross-border runs. Where a customer's duty cycle is dominated by gradients or very heavy gross weights, a numerically higher ratio can be specified instead.

Front and rear leaf-spring suspension is rated 3/5 — a lightened multi-leaf setup that keeps the load rating while filtering road harshness better than a conventional pack, so both the cargo and the driver benefit.

TX-F Right-Hand-Drive Cab, 600 L Tank, ABS and Full Air Brakes

The TX-F cab is a factory RHD layout with a single bunk and air conditioning as standard. Ergonomics and forward visibility are designed for long-distance driving, and the bunk makes this tractor truck usable for overnight line-haul work without hotel stops.

Protection is deliberately heavy-duty for export conditions. A high-mounted metal bumper is fitted together with a metal bumper guard grille and front and rear lamp guards, which keep flying stones and light impacts away from expensive components. A 50# reinforced kingpin fifth wheel is specified for trailer coupling.

Braking is a full air system with ABS as standard, so hard braking on a wet or gravel surface does not lock the wheels or swing the trailer. The 12R22.5 vacuum tyres use a longitudinal tread pattern in 18PR rating — a highway tread that resists punctures and wears evenly under sustained loaded running.

A 600 L aluminium alloy fuel tank extends range on cross-border corridors and reduces how often this HOWO tractor truck has to refuel in transit.

Customisation Options for Fleet and Dealer Orders

The base specification of this HOWO TX tractor truck is a complete working unit, but the platform is modular for operators who need something more specific.

Larger or dual fuel tanks can be specified for routes with long gaps between reliable fuelling points, extending range beyond the standard 600 L aluminium tank. Tyre specification can be changed to a mixed tread pattern where tarmac is not the only surface, while retaining the standard longitudinal highway tread for pure road work. A Parker coarse fuel filter with water separator can be added for markets with inconsistent diesel quality. Paint is available in fleet colours — including China Red, Engineering White and Aurora Blue — with free customised door lettering so units arrive already branded for the operator.

For dealers and fleet buyers ordering in volume, HiCA AUTO also supplies OEM spare-parts packages as a commercial alternative to straight price discounting, and can prioritise vessel booking so RHD units ship on schedule.

Frequently Asked Questions

Is this a genuine factory right-hand-drive truck or a local conversion?

It is a factory RHD unit produced on SINOTRUK's TX line. The steering gear, instrument panel, wiring and pedal layout are integrated during assembly rather than modified afterwards, so there is no converted-cab wiring or steering compromise. The model code ZZ4257N324GB1R identifies it, and spare parts can be ordered against that code.

Is 371 HP with a 3.70 axle ratio enough for high-speed heavy hauling?

Yes for line-haul duty. The 3.70 ratio is a highway ratio chosen to keep engine rpm low at cruising speed for better fuel economy, and the WD615.47 delivers its torque from low rpm. If your route is dominated by long climbs or very high gross weights, tell us your hauling weight and we can quote a numerically higher axle ratio instead.

Will a Euro II mechanical-pump truck clear customs in my country?

Most mainstream right-hand-drive markets in East Africa, Southern Africa and Southeast Asia still accept Euro II or Euro III for heavy trucks, but import regulations change and enforcement differs by port. HiCA AUTO confirms the destination country's current import standard for the specific model before you commit, and we do not quote on assumed compliance.

Can I order more than one unit, and what do I need to provide for a quotation?

Yes. To quote accurately we need six items: destination country and port, confirmation that the unit must be RHD, hauling weight and duty cycle, preferred axle ratio, target model year and whether you are an end-user fleet or a dealer. Quotations are issued on FOB or CIF terms with a 30 % + 70 % payment structure.

What forms of support come with an order?

Documentation is prepared for export including the OEM right-hand-drive authorisation certificate and chassis inspection report on request, and multi-language marketing material is available for dealers. Please contact us for the after-sales service scope that applies to your destination market.
