For the rear spring, end A has an opening of 3 (flat), and end B has an opening of 15 (non-flat). The surfaces of the coil springs undergo shot blasting treatment to enhance surface sturdiness and extend the service life. After production, the coil spring products are subjected to pressure treatment to eliminate excess internal force, preventing deformation or breakage of the coil springs during use. The coil springs with surface strengthening treatment feature a solid structure.
