Supplier's note

  1. Technical Breakthroughs:

    • Sup9 Steel: Delivers 20% higher tensile strength than standard steel, enabling heavier payloads.
    • Parabolic Design: Reduces leaf stack friction by 15%, minimizing wear and maintenance.
    • Modular Customization: Adjustable parameters allow precise tuning for niche applications like firetrucks or heavy-duty buses.

  2. Version Selection Guide:

    • Base Model: Ideal for standard commercial trucks (e.g., MAN, DAF) operating on paved roads.
    • Advanced Model: Perfect for buses or trucks needing extra durability (e.g., Renault 3000 series) in mixed terrain.
    • Pro Model: Designed for extreme conditions—firetrucks or off-road haulers benefit from its tripled corrosion resistance and 6.5-ton capacity. With the Pro’s enhanced fatigue life, you can extend maintenance intervals by up to 30%.
