They feature pre-set damping valves and variable stiffness springs which enhance ride comfort while preserving the vehicle's original height. Additionally, racing damping oil ensures stable operation across varying temperatures. Each front coil-over is equipped with OEM-standard top mounts, allowing for quick installation. Features 1. Preset For Optimal Damping : Optimal damping preset ensures the piston to provide sufficient damping force at various displacements, achieving a more comfortable riding experience compared to the OEM setting. 2. High-tensile Springs : Use variable stiffness springs to effectively balance between comfort and support, improving handling and stability at corners. 3. Equipped with OEM-Standard Top Mounts: Designed for quick, no-modification installation, the OEM-standard top mount uses superior rubber to reduce noise, vibration, and harshness. 4. Upgraded Damper Oil: The high-viscosity index racing damping oil provides stable damping characteristics and reduced viscosity changes across varying temperatures. 5. Excellent Sealing: Constructed with high-quality sealing materials to effectively prevent leakage and enhance efficiency. 6. Lower Mount: Made from heavy-duty 20# steel with a consistent thickness of electrophoretic paint finish, it ensures excellent corrosion resistance. 7. Twin-Tube Structure: The separate oil and gas chambers provide a longer-stroke damper than mono-tubedelivering excellent handling and control in various driving conditions. 8. Piston rod: Made from 45# reinforced steel and tested for 3 million cycles, featuring a corrosion-resistant coating to significantly extend service life. 9. Spring seat and locking ring: Made from anodized AL6061 aluminum, these lightweight, corrosion-resistant components offer excellent structural rigidity and minimize noise when used with rubber gaskets. 10. Dust cover: Made from TPV plastic, the extended dust cover offers superior protection for the damper by preventing dust intrusion and extending the service life of the damping system.
