HOWO TX 400HP 4×2 Tractor Truck Head
Efficient 4×2 prime mover for long-distance and regional freight
HOWO TX 400HP 4×2 Tractor Truck Head
The HOWO TX 400HP 4×2 Tractor Truck Head pairs a 400HP Weichai powerplant with a heavy-duty 12-speed gearbox and a high-roof TX cabin — designed for dependable container transport, intercity logistics and medium-long haul operations.

Detailed Product Description :
Designed for professional fleets, the HOWO TX 400HP 4×2 combines proven powertrain technology with operator-focused ergonomics to deliver consistent performance on highways and regional routes. At its heart sits the Weichai WP10H400E62 9.5L engine producing 400HP and 1900 Nm of torque, tuned to supply steady low-end pull for loaded starts and sustained cruising under GCW up to 35 tons.
The truck’s 4×2 layout and 3.08 final drive ratio prioritize fuel economy while maintaining adequate tractive effort for typical container and dry-freight duties. A robust 12-speed manual transmission provides precise gear control for hill climbs and heavy loads. Structurally, the frame has been reinforced to accept common trailer interfaces and to resist torsion on long hauls; the MCY13JGS rear axle and ABS-enabled air brake system contribute to predictable handling and stopping distances under load.
The TX high-roof cab emphasizes driver productivity: air-suspended driver seat, automatic climate control, electric mirrors, power windows, integrated GPS and reduced-cabin noise for less fatigue during multi-day runs. A 400-liter aluminum fuel tank reduces refueling stops, improving utilization on long runs. Altogether, the HOWO TX 400HP 4×2 is a practical, cost-aware choice for operators seeking proven reliability and low operating cost per ton-km.
