The Fuso Fighter FK series is built on a robust chassis designed to handle high torsional stress. Typically powered by a or similar 6-cylinder diesel engine, delivering between 180–210 hp of torque. Transmission:
Standard Fuso FK chassis are typically 4.5 to 6 meters long. For log carriers or heavy dump trucks, SBN Karoseri often performs a chassis extension. Using a process called "splicing" with grade 8.8 bolts and double-layered reinforcement plates, the wheelbase is safely extended to accommodate larger bodies without compromising torsional rigidity.

SBN Karoseri utilizes high-tensile steel (HTS) with thicknesses ranging from 4mm to 6mm for the main rails versus standard 8mm mild steel. This material science approach reduces the empty weight (tare weight) by approximately 500kg to 1 ton. For every kilogram saved on the body, one kilogram is added to legal payload.
