coilover coil springs

Specification: 12.2*108/147/112*365*4.5
Material: 55SiCrA
The coil spring 82001H08 is applicable to the GAC Honda third-generation Fit (GK5, 2014-2021) and is intended for the front axle.
Wire diameter: Ø12.2 mm. Outer diameter at End A: 108 mm, outer diameter at End B: 112 mm, center outer diameter: 147 mm. Height: 365 mm. Number of coils: 4.5. End A features one transition coil with a 23 mm gap (non-passing), while End B has slightly more than one transition coil with a 13 mm gap (flat). This spring has a unit weight of 1.6 kg.
The compression/rebound force of the coil spring 82001H08 exhibits a linear relationship with the deformation, resulting in highly response of the suspension system. When a vehicle traverses uneven road surfaces, the coil spring can absorb impacts smoothly, avoiding harsh jarring and providing a soft damping effect.
Compared to traditional leaf springs, this coil spring more efficiently filters out high-frequency, low-amplitude vibrations from the road surface, such as minor imperfections on asphalt roads, significantly enhancing ride comfort.
This coil spring is typically installed separately and independently from the shock absorber. Its relatively lightweight contributes to a notable reduction in unsprung mass. The lower unsprung mass allows the wheels to maintain better contact with the road surface, reduces hopping over bumps, and consequently improves tire grip, thereby improving overall vehicle handling stability, steering response, and braking performance.
