32 suspension coil springs

Specification: 12.8*88/130/90*355*7.25
Material: 55SiCrA, 60Si2Mn, or other materials
Description:
This product is a coil spring, also known as a helical spring, which serves as a component for automotive shock absorbers. As one of the core accessories of a vehicle’s suspension system, a high-quality coil spring can enhance both riding comfort and handling stability. Take the coil spring shown in the picture above as an example, this coil spring in the picture is suitable for Toyota vehicle models, with a wire diameter of up to 12.8 mm, an A-end outer diameter of 88 mm, a B-end outer diameter of 90 mm, a middle outer diameter of 130 mm, a height of 355 mm, and a piece weight of approximately 2.49 kg. It is formed into a standard helical shape by heating to soften high-quality alloy steel and then bending the steel. To improve its corrosion resistance, shot blasting, outer-layer painting, or galvanization is typically employed.
Qingdao EVERLASTING is an enterprise specializing in the production of automotive suspension system components, and possesses advanced production equipment and exquisite process technologies. During the production process, strict quality control is implemented at every link: shot blasting not only ensures a smooth surface but also enhances the spring’s fatigue strength; a heat treatment process makes the internal structure of the spring more uniform, improving its mechanical properties; and standardized treatment ensures that every spring meets consistent and high-quality standards, providing reliable support for the stable running of vehicles. We pursue ultimate quality, have supplied a large number of high-quality automotive suspension system components to the automotive industry, and have won widespread recognition and praise in the market.
