Swift ID 65mm x 8" Coilover Springs, 9.0 KGF/MM

Swift's innovative designs have made them a staple in the performance tuning world. With over 90 years of experience in industrial spring manufacturing, Swift engineers have developed these coilover springs to be light, durable, and compliant while maintaining linear spring rates. Unlike many other springs that only offer a noticeable change in stiffness, Swift springs aim to provide a tangible increase in traction, smoother weight transfer, better ride quality, lower tire temperatures, and a more predictable feel. These specific coilover springs feature an 8-inch length and a 65mm inner diameter, with a spring rate of 9.0 KGF/MM, equivalent to 504 lbs/inch. They are manufactured using H5S.TW material, which is noted as being superior to silicone chrome steel. This advanced material allows for the use of fewer coils, contributing to reduced unsprung weight and an increased suspension stroke, ultimately improving performance and handling. Each order includes a pair of Swift springs. They come with a manufacturer standard warranty, ensuring quality and reliability.
