Description

This spring is crafted from K-Tuned's proprietary HS5.TW material, known for its durability and consistent performance characteristics. Key specifications include a 7-inch length, a 70mm inner diameter (2.76 inches), and a spring rate of 12.0kgf/mm (672 lbs/inch). The spring offers a usable stroke of 87mm (3.4 inches) and a maximum stroke of 111mm (4.4 inches), providing ample travel for dynamic suspension movement. This component is sold exclusively in pairs. It's important to note that the visual representation of the spring's color in images may not always correspond to its specific rate or ID, as color coordination is often based on the inner diameter. Ensure compatibility with your existing coilover system's specifications before purchase.
