To ensure the quality of our product, each production process, like raw material sourcing, heat treatment, surface protection, etc., is strictly controlled. This makes the ISO property class of the finished product reach 10.9, which guarantees long life span. In addition, all leaf spring center bolts must be corrected after quenching and tempering to ensure the perpendicularity of the rod portion and head part so as to facilitate assembly.
