Description

This specific model offers a 7-inch length, a 65mm inner diameter, and a robust spring rate of 12.0kgf/mm (672lbs/inch). It boasts a usable stroke of 83mm and a maximum stroke of 111mm, allowing for precise control over suspension travel. Constructed from Swift's proprietary HS5.TW steel, this coilover spring is noted for its superiority over traditional silicone chrome steel. This advanced material contributes to a more responsive and predictable feel, leading to tangible benefits such as increased traction, smoother weight transfer, and improved ride quality. The springs are also color-coordinated based on their inner diameter, adding a visual element to their design. These metric coilover springs are available in various rates to cater to different driving preferences and performance needs. They are sold exclusively in pairs. While the image shown may not perfectly reflect the exact length and rate of this specific spring, it serves as a color coordination guide based on the inner diameter.
