Product Description
Model: ZZ4257N324GB1R | Drive: 6X4 Right-Hand Drive (Factory RHD) | Emission: Euro II
The brand-new SINOTRUK HOWO TX 371 HP 6X4 Tractor Truck is engineered specifically for heavy-duty long-haul logistics and container transport across East Africa, Southern Africa, and Southeast Asia. Built on a original German MAN TGA technology chassis, this factory right-hand drive (RHD) truck offers exceptional fuel efficiency, low maintenance costs, and robust road performance.
Key Highlights & Features
Factory Right-Hand Drive (RHD): Built directly on the SINOTRUK assembly line (not an aftermarket conversion). Integrated steering gear, dashboard, and wiring harness ensure zero electrical or mechanical safety risks.
Fuel-Tolerant Engine (WD615.47): 371 HP Euro II mechanical injection engine—no urea (AdBlue/DEF) required. Highly tolerant of high-sulphur diesel, eliminating risk of engine derating or limp mode in remote areas.
HW19710 10-Speed Transmission: Twin-countershaft manual gearbox (10 forward + 2 reverse) designed to distribute shock loads smoothly during heavy uphill starts and high-speed highway cruising.
MAN TGA Chassis & Highway Axles: Features high-strength frame rails paired with MCJ12BGY single-reduction tandem rear axles (3.70 ratio) for high transmission efficiency (>98%) and optimized fuel burn.
Driver Comfort & Safety: TX-F cab with single sleeper bunk, air conditioning, full air brake system with ABS, EVB exhaust brake, high-mounted metal bumper, and stone guards.
Extended Range: Equips a large 600 L aluminium alloy fuel tank to reduce downtime on long-distance cross-border routes.
Options & Customization
Fuel Capacity: Optional dual or enlarged fuel tanks for ultra-long corridors.
Filtration: Optional Parker coarse fuel filter with water separator for low-quality fuel regions.
Custom Branding: Fleet paint colors available (China Red, Engineering White, Aurora Blue) with custom door lettering.
Gearing & Tyres: Alternative axle ratios for steep mountain terrain and mixed-tread tyres for off-tarmac operation.
Frequently Asked Questions (FAQ)
Q1: Is this a genuine factory RHD or a converted truck?A: It is a 100% original factory-built RHD unit from SINOTRUK's TX assembly line. All components (steering, harness, pedals) are natively integrated, ensuring reliable performance and easy spare parts ordering via model code ZZ4257N324GB1R.
Q2: Is the 371 HP engine and 3.70 axle ratio suitable for heavy hauling?A: Yes. The 3.70 axle ratio is optimized for flat highway long-haul logistics to keep RPM low and maximize fuel economy. For routes with heavy gradients or extreme gross weights, alternative gear ratios are available upon request.
Q3: How can I request a quotation for fleet or dealer orders?A: Contact HiCA AUTO for FOB or CIF pricing. Please provide your destination port, required hauling weight, duty cycle, and target order quantity for an accurate quote.
