6-Inch Coil Spring 7.0 kgf/mm

The K-Tuned metric coilover spring is a high-performance suspension component crafted from proprietary HS5.TW material, designed to offer the options needed for both daily drivers and race cars. This specific spring measures 6 inches in length with a 60mm inner diameter, providing a spring rate of 7.0 kgf/mm, equivalent to 392 lbs/inch. Engineered for precise suspension tuning, this coilover spring offers a usable stroke of 89mm and a maximum stroke of 96mm. The product page notes that the color-coordinated image may not precisely match the depicted length and rate, as colors are primarily assigned based on inner diameter. These springs are exclusively sold in pairs. K-Tuned aims to provide a wide variety of Swift metric coilover springs to meet diverse application needs. The HS5.TW material is a key feature, contributing to the spring's performance and longevity. The 60mm inner diameter and 6-inch length are specific dimensions that allow for compatibility with certain coilover systems, making it a direct replacement or upgrade option for many setups. When selecting a coilover spring, factors such as desired ride height, handling characteristics, and intended use (daily driving versus track performance) are crucial. This particular spring's specifications suggest it is suited for enthusiasts looking to fine-tune their vehicle's suspension for improved responsiveness and stability. The 7kgf/mm rate offers a moderate increase in stiffness over stock springs, contributing to reduced body roll and better road feel.
