Dominican HOWO 6x4 371hp Tractor Truck

AORUN | 2026-7-28

During their technical review in Jinan, the Dominican clients outlined their primary operational demands along the Santo Domingo to Santiago freight corridor and surrounding mountain routes: Will the chassis resist salt corrosion from coastal air? Can the 371hp engine handle heavy gradient climbs without overheating? And how do we ensure uninterrupted spare parts support at a competitive price?

Our export engineering specialists presented targeted technical solutions:

1. Legendary WD615.47 Engine (Proven Mechanical Reliability)

Caribbean routes require dependable pulling power without delicate, overly complex electronic sensors.

The heavy duty HOWO 10 wheeler 371hp for sale is powered by the classic Euro II 9.7L inline-6 turbocharged mechanical diesel engine. Renowned across Latin America, it easily tolerates regional diesel fuel variations and allows fleet mechanics to perform low-cost, straightforward maintenance.
Matched with a heavy-torque HW19710 10-speed manual transmission and a heavy-duty power take-off (PTO) system, the powertrain provides exceptional low-rpm torque for effortless mountain climbing under maximum payloads.

2. Tropical Salt-Spray Anti-Corrosion & Severe-Duty Axles

Marine & Coastal Protection: Because the Dominican Republic features a high-salinity, humid coastal atmosphere, chassis produced at our Jining Liangshan commercial vehicle manufacturing base undergo an intensive marine-grade protection process—including full shot-blasting, multi-layer zinc epoxy priming, and a thick anti-corrosion wax coating prior to shipping.
Heavy Off-Road Traction: Equipped with reinforced HC16 reduction axles (16-ton cast steel double-reduction driving axles) featuring inter-wheel and inter-axle differential locks. This guarantees maximum traction when hauling heavy trailers over loose gravel or muddy quarry tracks.

3. Multi-Trailer Fifth Wheel Coupling

Fitted with a heavy-duty JOST 2.0-inch or 3.5-inch fifth wheel, this prime mover provides seamless heavy duty 3 axle semi trailer coupling. It offers outstanding operational versatility—easily switching between container chassis, dump trailers, or flatbeds.

Partnering with a reliable HOWO 371hp prime mover supplier that offers an honest Sinotruk HOWO 6x4 tractor truck 371hp price is essential for maintaining strong profit margins. Aorun eliminates agency markups and supply chain uncertainty:
