Overview

Produced from Swift's proprietary HS5.TW material, this spring offers superior strength and durability compared to standard silicone chrome steel.
Show original supplier description
Crafted from Swift's proprietary HS5.TW steel, this material is noted for its superiority over traditional silicone chrome steel, offering improved strength and longevity for both daily driving and track applications. This specific coilover spring features an 8-inch length with a 65mm inner diameter and a spring rate of 10.0kgf/mm (560 lbs/inch). It provides a usable stroke of 100mm and a maximum stroke of 125mm, designed to deliver increased traction, seamless weight transfer, and better ride quality. The springs are color-coordinated based on their inner diameter, offering a wide variety of lengths and rates to suit diverse needs. Swift Springs are sold exclusively in pairs. While specific vehicle fitment is not detailed, these springs are intended to replace existing coilover springs and are available in various configurations to optimize suspension setups for a wide range of vehicles, from daily drivers to race cars.
