Description

The Swift Springs Metric Coilover Spring offers a high-performance upgrade for your vehicle's suspension system. Engineered with Swift's proprietary HS5.TW material, these springs are designed to deliver superior performance and durability compared to standard silicone chrome steel. Each spring measures 8 inches in length with a 65mm (2.56 inch) inner diameter and a spring rate of 7.0kgf/mm (392 lbs/inch). The usable stroke is 115mm (4.5 inches), with a maximum stroke of 127mm (5.0 inches). This combination of specifications aims to provide increased traction, seamless weight transfer, improved ride quality, and more predictable handling, whether for daily driving or racing applications. Swift Springs are color-coordinated based on their inner diameter, offering a wide variety of lengths and rates to suit specific build needs. These springs are sold exclusively in pairs.
