{"product_id":"metric-coilover-spring-9-inch-70mm-id-9-0-kgf-mm","title":"Metric Coilover Spring 9-inch 70mm ID 9.0 kgf\/mm","description":"Drawing on over 90 years of industrial spring manufacturing experience from Swift, these springs aim to provide a noticeable increase in traction, smoother weight transfer, and a more predictable feel. They are constructed from Swift's proprietary H5S.TW material, which is noted for being superior to silicone chrome steel. This advanced material allows for a design with fewer coils, resulting in reduced unsprung weight and an increased stroke.\n\nThis specific spring offers a 9.0 kgf\/mm (504 lbs\/in) spring rate, a usable stroke of 116mm (4.6 inches), and a maximum stroke of 143mm (5.6 inches), with a maximum load capacity of 1285 kgf (2833 lbs). The 70mm inner diameter and 9-inch length are part of Swift's metric line, designed to reduce confusion and better cater to the needs of the sport compact and road race markets.\n\nThese springs are sold in pairs and are considered a universal fitment, though it is essential to verify compatibility with your specific coilover system.","brand":"K-Tuned","offers":[{"title":"Default Title","offer_id":52869732335928,"sku":"Z70-228-090","price":238.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/688008549.webp?v=1787917967","url":"https:\/\/store.motormia.co\/products\/metric-coilover-spring-9-inch-70mm-id-9-0-kgf-mm","provider":"MOTORMIA","version":"1.0","type":"link"}
