Description

The K-Tuned Metric Coilover Spring, part number Z60-228-090, offers a versatile solution for suspension tuning, suitable for both daily driving and track use. This 9-inch spring is engineered with a 60mm inner diameter and a 9.0kgf/mm (504lbs/inch) spring rate, providing a balance of comfort and performance. Constructed from K-Tuned's proprietary HS5.TW material, this spring is known for its superior strength compared to traditional silicone chrome alloys, ensuring durability and consistent performance under demanding conditions. The spring offers a usable stroke of 109mm (4.3 inches) and a maximum stroke of 139mm (5.5 inches). These springs are sold exclusively in pairs. Please note that the image shown may not precisely reflect the length and rate of this specific spring, as the visual color coordination is based on the inner diameter.
