Product Details

Swift Springs Metric Coilover Springs in 62mm ID and 5.5" (140mm) length deliver the traction, handling, and consistency that competitive drivers rely on. Engineered for coilover suspension systems using metric-sized dampers, these 62mm Swift coilover springs are manufactured in Japan from proprietary H5S.TW high-tensile alloy steel, providing a significant performance advantage over conventional silicone chrome springs. With fewer coils per spring, Swift reduces unsprung mass and increases usable stroke, translating to better grip, smoother weight transfer, and more predictable handling at the limit.

For over 90 years, Swift Springs has led the industry in precision spring manufacturing. Unlike conventional coilover springs that only offer a stiffer or softer ride, Swift Springs coilover springs provide measurably increased traction, smoother weight transfer, better ride quality, lower tire temperatures, and a more predictable driving experience. All Swift coilover springs are manufactured using proprietary H5S.TW alloy, which is far superior to typical silicone chrome steel and allows Swift to wind a more responsive spring with fewer coils — resulting in reduced unsprung weight and increased usable stroke. Swift metric coilover springs are available in inner diameters from 60mm to 70mm, lengths from 102mm (4") to 254mm (10"), and spring rates to suit any application from street performance to professional motorsport.
