The advanced suspension system and multiple axle ratio options (4.42/4.8/5.73) allow for customization based on specific speed and power requirements.
Driver Comfort & Global Versatility
The European-style high-roof cab focuses on long-haul productivity, featuring a four-point fully floating design to minimize vibration. It includes an ergonomic seating layout, wide-angle visibility, and electric heated mirrors for enhanced safety. Available in both LHD and optional RHD configurations, this model is a trusted solution for international logistics fleets across Africa, Southeast Asia, and the Middle East.
