60mm I.D. x 9-inch Coilover Spring 7 kgf/mm

Designed with a 60mm inner diameter and a 9-inch length, these springs offer a 7 kgf/mm spring rate, providing a balance between comfort and aggressive performance. The springs are constructed from Swift's proprietary H5S.TW material, which surpasses silicone chrome steel in performance. This advanced material allows for a more compact spring design with fewer coils, directly contributing to a reduction in un-sprung weight and an enhancement in suspension travel and responsiveness. Swift offers a comprehensive range of metric springs with inner diameters from 60mm to 70mm, lengths from 5 inches to 11 inches, and rates from 3 kgf/mm to 34 kgf/mm. This variety ensures a suitable option whether the application is for daily commuting or dedicated track use. Key specifications for this particular pair include a 60mm ID, 9-inch length, 7 kgf/mm spring rate, a usable stroke of 4.8 inches, and a maximum stroke of 5.4 inches. The product is sold only as a pair, with each box containing two springs. While these springs are listed with universal applications, it is recommended to verify compatibility with specific coilover systems and vehicle setups.
