front coil spring

Specification: 13.4*114/120*340*7
Material: 55SiCrA
The coil spring R.FH12-020 is applicable to the Toyota Reiz or its Japanese domestic sibling model, the Toyota Mark X. It is a mainstream model in the modification market, commonly used to lower the vehicle body and enhance handling performance.
Wire diameter: ∅13.4 mm, outer diameter at end A: 114 mm, outer diameter at end B: 120 mm, height: 340 mm, number of coils: 7. This spring is right-handed, with a unit weight of 2.6 kg.
The wire diameter of the coil spring R.FH12-020 is greater than that of coil springs used in economy cars, which is directly related to the spring’s stiffness.
The K-value of the coil spring R.FH12-020 is higher than that of comfort-oriented mid-size sedans like the Toyota Camry, ensuring a superior driving feel.
There is slight friction between the coils of the coil spring R.FH12-020, which inherently provides damping. When combined with rubber top seats, buffer blocks, and other components, it can effectively dampen high-frequency vibrations and road noise.
The coil spring R.FH12-020 can be directly fitted over a telescopic shock absorber to form an integrated strut consisting of the spring and shock absorber. This reduces the number of parts, improves the versatility of the suspension module, and enhances assembly efficiency.
Coil springs are critical components affecting driving safety. Poor-quality coil springs risk breaking, with unthinkable consequences. The coil springs produced by EVERLASTING strictly comply with automotive industry quality system standards such as QS9000/TS16949. They undergo millions of fatigue tests to ensure there is no risk of breakage, providing a solid foundation for your driving safety.
