Show original supplier description
With over 90 years of experience in industrial spring manufacturing, Swift has developed this spring using their proprietary H5S.TW material. This advanced alloy is superior to standard silicone chrome steel, allowing for a lighter spring with fewer coils, which reduces unsprung weight and increases suspension stroke. This specific coilover spring features a 60mm inner diameter and a 6-inch length, with a robust spring rate of 30.0 kgf/mm (equivalent to 1,680 lbs/inch). The design prioritizes increased traction, smoother weight transfer, and a more predictable feel, while also contributing to better ride quality and potentially lower tire temperatures. The spring offers a usable stroke of 56mm and a maximum stroke of 71mm, with a maximum load capacity of 4,709 lbs. Swift's commitment to quality ensures a product that is not only compliant but also durable, aiming to provide a significant improvement over standard spring setups, whether for daily driving or track use.
