Technical specifications

Customization guide

Adjust leaf count, thickness, and curvature to meet specific requirements:

• Leaf Count: Increase for higher load capacity (e.g., 15 leaves for 12-ton trailers).
• Thickness: Thicker leaves enhance durability in off-road conditions.
• Curvature: Tailored arch design for optimal weight distribution.

Supplier's note

1. Technical Breakthroughs:

   • The Pro Model’s 1,000-hour salt-spray resistance (triple industry norms) enables safe use in marine or industrial environments.
   • Advanced Model polymer bushings reduce friction by 20% compared to traditional metal bushings.
   • Base Model’s SAE J2237 compliance ensures seamless integration with global truck manufacturers like BPW and SAF.

2. Optimal Version Selection:

   • Pro Model: Ideal for heavy haulers (e.g., logging trucks) needing 13,000 lbs capacity and extreme corrosion resistance.
   • Advanced Model: Best for medium-duty trailers (e.g., agricultural transport) requiring improved shock absorption without premium costs.
   • Base Model: Suitable for standard commercial trucks operating in moderate conditions, offering cost-effective reliability.

With the Pro Model’s 30% higher load capacity than base versions, you can safely tow heavier payloads while maintaining structural integrity. The Advanced Model’s 20% faster energy dissipation ensures smoother rides on rocky terrains.
