XIAYI Wear-Resistant Hardened Piston Rod is designed for automotive shock absorber systems requiring stable dimensional accuracy, surface hardness, and long-term wear resistance. Manufactured in China under a quality management system compliant with IATF 16949:2016, it uses high-grade alloy steel, precision CNC machining, hard chrome plating, and multi-stage grinding to achieve consistent surface performance.

XIAYI Corrosion-Resistant Chrome Rod is designed for automotive shock absorbers exposed to humidity, salt spray and corrosive road conditions. With a chrome thickness of 15--25 μm, surface roughness of Ra 0.4--0.6 μm and straightness of ≤0.02 mm/m, it provides reliable protection against rust, pitting and coating peeling while maintaining stable dimensional accuracy.

XiaYi High Strength Shock Absorber Coil Spring is designed for vehicles and equipment requiring stable suspension support under repeated loads, including passenger cars, EVs, commercial vehicles and construction machinery. Made from high-strength alloy spring steel, it combines controlled spring stiffness, precision coiling, stress relief and shot peening to maintain load-bearing performance during long-term operation.

XiaYi Heat-Treated Alloy Steel Coil Spring is designed for vehicle suspension and machinery applications where stable elasticity, fatigue resistance and material strength are required. Four material options, including 60Si2Mn, chrome-silicon, chrome-vanadium and special alloy steel, allow buyers to select the appropriate performance according to vehicle load, operating conditions and environment.

XiaYi Fatigue-Resistant coil spring is designed for vehicle and machinery suspension systems exposed to repeated loads and vibration. Made from high-purity alloy steel and processed through precision forming, heat treatment and surface strengthening, it provides up to 1.2 million fatigue cycles, 95% elastic retention and 500-hour salt spray resistance. The spring helps reduce fatigue fracture, permanent sagging, suspension noise and fitting variation.

For suspension systems where dimensional accuracy directly affects assembly and load distribution, XiaYi Precision-Wound Coil Spring is manufactured with CNC-controlled winding, precision end grinding and multi-stage process inspection. With a spring rate tolerance of ±3%, end-face flatness of ≤0.03 mm and fatigue verification of ≥1 million cycles, it is suitable for passenger cars, EVs, commercial vehicles and construction machinery.
