back coil springs

Specification: 10.9*85/112/86*360*7
Material: 55SiCrA
The coil spring 52441-TM4-C01 is an OEM replacement coil spring specifically designed for the rear suspension of the GAC Honda third-generation City (City GM6, 2015-2022).
Wire diameter: Ø10.9 mm. Outer diameter at End A: 85 mm, outer diameter at End B: 86 mm, center outer diameter: 112 mm. Height: 360 mm. Number of coils: 7. Both End A and End B feature 1.25 transition coils with a flat leakage. The spring has a unit weight of 1.55 kg.
As the suspension system is directly related to driving safety, this coil spring has undergone rigorous bench testing, fatigue testing, and on-vehicle road testing. It can ensure stable vehicle posture and reliable tire grip under various load conditions (such as carrying rear passengers, or cargo in the trunk), thereby safeguarding driving safety.
This high-quality coil spring, through precision heat treatment and shot peening, offers an extremely high fatigue life, and can withstand millions of compression and rebound cycles without fracture.
Throughout the vehicle’s entire lifecycle, the coil spring exhibits minimal stiffness and performance degradation, allowing it to maintain the vehicle’s original suspension characteristics and safety over a long term.
The coil spring’s structure enables it to provide significant elastic force and travel within a relatively compact space, meeting your vehicle’s load-bearing requirements.
The compact cylindrical structure of this coil spring facilitates easy chassis layout, freeing up more space for the engine bay, passenger cabin, and trunk.
