Product Details
Swift Springs Standard Conventional Springs in 5" OD and 18" length provide maximum stroke for long-travel racing suspension setups. These 5" OD Swift conventional race springs are manufactured in Japan from proprietary H5S.TW high-tensile alloy steel, delivering consistent rate behavior and fatigue resistance through extended free lengths commonly used in dirt track and off-road racing applications.
For over 90 years, Swift Springs has led the industry in precision spring manufacturing. Their 18" conventional springs are designed for applications requiring the most possible usable stroke. All Swift Springs use H5S.TW alloy for superior fatigue life compared to standard silicone chrome steel.
