Description

The Swift Springs metric coilover spring (Part Number: Z70-228-080) is engineered for performance and daily driving applications. Constructed from Swift's proprietary HS5.TW material, this spring offers superior performance compared to standard silicone chrome steel. This specific coilover spring measures 9 inches in length with a 70mm (2.76-inch) inner diameter and a spring rate of 8.0kgf/mm (448 lbs/inch). It features a usable stroke of 117mm (4.6 inches) and a maximum stroke of 148mm (5.8 inches). The springs are color-coordinated based on their inner diameter. Swift Springs aims to deliver a noticeable difference in vehicle dynamics, including increased traction, seamless weight transfer, improved ride quality, and more predictable handling. The springs are sold in pairs.
