Frequently Asked Questions

Q: What materials are best for LCV medium duty leaf springs?

We utilize high-grade 60Si2Mn, SUP9, and 51CrV4 spring steels, which offer the best combination of elasticity, fatigue resistance, and load-bearing strength for commercial vehicles.

Q: Can you manufacture leaf springs based on a physical sample?

Yes, we provide comprehensive reverse engineering services. You can send us a physical sample, and we will analyze its dimensions and material properties to produce an exact or improved match.

Q: What is the difference between parabolic and multi-leaf springs?

Multi-leaf springs consist of several leaves of varying lengths, while parabolic springs have a tapered profile. Parabolic designs generally offer a smoother ride and lower weight without sacrificing load capacity.

Q: How do you ensure the corrosion resistance of the springs?

We offer multiple surface treatments including high-quality painting, electrophoretic coating, and powder coating, all of which are verified through rigorous salt spray testing.

Q: Which LCV models are compatible with your medium duty springs?

Our products are compatible with a wide range of vehicles, including the Toyota Hilux, Ford Ranger, Isuzu D-Max, Mitsubishi L200/Triton, and Nissan Navara, among others.

Q: What quality certifications do your manufacturing processes hold?

Our production facility is ISO 9001 and IATF 16949 compliant, ensuring that every component meets strict automotive industry standards for safety and reliability.
