HS5.TW Coil Springs

Constructed from Swift's proprietary HS5.TW material, these springs offer a superior alternative to traditional silicone chrome steel. This advanced material allows for a more efficient spring design with fewer coils, resulting in a reduction in unsprung weight and an increase in usable suspension stroke. The metric sizing (65mm ID, 10-inch length, 14 kgf/mm spring rate) is intended to reduce confusion for enthusiasts working with common sport compact setups. This specific coilover spring pair features a 65mm inner diameter and a 10-inch length. The spring rate is set at 14 kgf/mm, which equates to approximately 784 lbs/inch. The usable stroke is measured at 3.9 inches, with a maximum stroke of 6.2 inches, providing ample travel for aggressive driving conditions. These springs are sold exclusively as a pair. Swift offers a broad range of metric coilover springs, with inner diameters from 60mm to 70mm, lengths from 5 inches to 11 inches, and spring rates spanning from 3kg to 34kg. This wide selection ensures that drivers can find a spring setup suited for various applications, from daily commuting to dedicated track use. The springs come with a manufacturer's standard warranty.
