About the HOWO NX 6×4 Prime Mover
The HOWO NX 6×4 Prime Mover is a tractor unit for trailer and container haulage. The configuration documented here, model ZZ4257S3241W, uses the Sinotruk WD615.47 engine: a 9.726 L, six-cylinder, turbocharged and intercooled diesel rated at 371 HP and 1,500 Nm.
A 10-speed HW19710 gearbox, a 430 mm diaphragm-spring clutch and a high-strength U-profile frame carry the drivetrain. The high cab has a double berth, an air-suspension driver seat and a fully floating four-point cab suspension, and the 600 L tank sits on the off side of the chassis.
It suits transport and logistics businesses running trailers and containers on routes such as Mombasa to Nairobi, Nakuru and Eldoret. Other NX configurations are listed at 380 HP, so Joshua confirms the exact unit before you decide.
