Cummins LK375 33 · 12-speed FAST · Dana single-reduction axle 4.44 · GCW 49 t
The T31Y is purpose-built for medium- and long-distance line-haul of bulk and container cargo in hot, humid African climates. Its proven Cummins + FAST powertrain keeps total cost of ownership low while the lightweight Dongfeng VL platform carries more payload under the same 49 t GCW limit.

Engine and gearbox B10 life exceeds 1.5 million km. Full-body electrophoresis painting and multi-layer anti-corrosion coating are engineered for African heat, humidity and coastal salt air.
High-strength steel cab designed to European crash standards maximises survival space; simple mechanical suspension keeps maintenance costs low.
The classic Cummins + FAST powertrain is widely serviced across Africa; parts are inexpensive and available everywhere, protecting resale value.
