OEM Z-Type Leaf Spring Air Connector for Trailer Air Suspension System
How do we guarantee quality?
Firstly, We ensure quality from the source
Our spring flat bar is from the top 1 steel material supplier in China.
Secondly, Advanced Heat Treatment Technology
We have been deeply engaged in the leaf spring industry for many years, accumulating extensive experience and building a professional team of highly skilled and seasoned engineers. In the field of heat treatment, we possess not only advanced technology but also rich practical experience, enabling us to strictly control every production process. This ensures the superior quality and reliable performance of our leaf springs, providing customers with products and services they can trust.
The heat treatment process of leaf springs is a critical step to enhance their strength, toughness, and fatigue life. It typically includes three main procedures: heating, quenching, and tempering. First, the leaf spring is heated to a specific austenitizing temperature (usually between 850°C and 950°C) to transform the internal structure of the steel into a uniform austenite structure. Next, rapid cooling (quenching) is performed, usually using oil as the cooling medium, to form a high-hardness martensite structure. Finally, tempering is carried out by heating the leaf spring to an appropriate temperature (such as 400°C-600°C) and holding it for a certain period, which helps relieve internal stress while improving toughness and fatigue resistance. Through a scientifically designed and well-executed heat treatment process, the leaf spring can achieve high strength while maintaining excellent elasticity and durability, meeting the demands of vehicles under complex working conditions.
Thirdly: Strict Quality Inspection
We adopt comprehensive and rigorous testing processes to ensure that the quality and performance of the leaf springs meet the standards.
Our products have passed ISO9001 international quality standard certification. We implement all-round quality control from raw materials to finished products. The quality inspection system tracks the whole process and matches the finished product extreme performance test to fully ensure product quality.
The leaf spring guiding arm is a critical component in a vehicle's suspension system. Its primary function is to connect the axle and the chassis, guide the axle to maintain the correct trajectory during vertical motion, and bear the longitudinal and lateral forces generated during vehicle operation. The guiding arm is typically used in conjunction with leaf springs to jointly perform shock absorption and load-bearing functions. It is made of high-strength materials, offering excellent fatigue resistance and durability to meet the demands of complex road conditions. The design of the guiding arm emphasizes structural strength and geometric precision to ensure vehicle stability and handling performance while reducing wear and maintenance costs. It is one of the key components that ensure vehicle safety and comfort.

Shandong Xiaocheng Auto Parts Co., Ltd. is a modern private enterprise engaged in the design, development and production of automobile leaf spring. The company has been operating for more than ten years, focusing on the production and development of the existing leaf spring 2 production lines (annual output of more than 30,000 tons).
The company is a domestic supporting enterprise, and has close cooperation with FAW Jiefang and Sinotruk. Our raw material cooperation manufacturers include Jiangyin Xingcheng, Qingdao Special Steel, Fangda Special Steel and other large domestic steel mills to ensure the quality of raw materials.
Our production process is all in accordance with the original process, the use of rapid quenching oil for heat treatment, to ensure the level of metallographic structure. Surface shot peening, using stress shot peening machine, effectively ensure residual stress. The paint is treated by electrophoretic spraying, and the salt spray test reaches 400 hours. It has successfully passed various bench and road tests, and can be customized according to the drawings and corresponding requirements.
