Description

The K-Tuned Metric Coilover Spring offers a performance upgrade for various applications, from daily driving to track use. This spring is constructed from Swift's proprietary HS5.TW material, which is noted for its superior quality compared to traditional silicone chrome steel, allowing for fewer coils while maintaining strength and performance. Key specifications for this particular spring include a 7-inch length and a 60mm inner diameter. The spring rate is precisely tuned at 14.0kgf/mm, which equates to 784 lbs/inch. It also offers a usable stroke of 78mm (3.1 inches) and a maximum stroke of 104mm (4.1 inches), providing a balance of ride comfort and handling capability. These coilover springs are specifically designed to be compatible with systems requiring a 60mm inner diameter and are sold exclusively in pairs.
