Coil spring for car

Specification: 12.4*122/152/129*325*4.4/11.9*120/150/127*325*4.4
Material: 55SiCrA or 60Si2Mn or 60CrMnA
This product is suitable for the New Tiida, a compact passenger car under Dongfeng Nissan. The New Tiida has achieved strong sales volume, so the coil springs applicable to this model have become one of our mainstream sales accessories.
The model is equipped with matching front and rear coil springs. The specification of the front spring is 12.4*122/152/129*325*4.4, and the specification of the rear spring is 11.9*120/150/127*325*4.4. Both the front and rear springs of this product feature irregular coil winding. The outer diameters of end A and end B are uniformly smaller than the middle outer diameter. For the front spring, the opening at end A is non-flat, with 0.8 variable-diameter coils; end B also has 0.8 variable-diameter coils. For the rear spring, end A has 1 variable-diameter coil with a non-flat opening of 25 mm, and end B also has 1 variable-diameter coil with a non-flat opening of 26 mm. The front and rear springs work together to ensure the vehicle’s stability during driving. The irregular coil shape increases the buffer for elastic deformation when the vehicle is in motion. This is particularly evident on bumpy roads, which enhances the comfort of both drivers and passengers while reducing vibrations caused by poor road conditions.
In other aspects, the metal process of these two types of coil springs meets standards. With perfect metal element composition, production by precision equipment, and strict shot blasting treatment, the service life and usage limit of these two coil springs are extended. Therefore, these two coil springs perform excellently in terms of service life, stiffness, elastic limit, shock absorption ability and other factors.
