{"product_id":"70mm-id-x-6-inch-h5s-tw-coil-spring","title":"70mm ID x 6-Inch H5S.TW Coil Spring","description":"The Swift Springs Metric Coilover Spring, with a 70mm inner diameter and 6-inch length, is engineered to deliver superior traction, handling, and consistency for competitive driving. Constructed from proprietary H5S.TW high-tensile alloy steel in Japan, these springs offer a distinct performance edge over conventional silicone chrome springs.\n\nSwift's design utilizes fewer coils, which reduces unsprung mass and increases usable stroke. This translates to enhanced grip, smoother weight transfer, and more predictable handling, even at the limit. The proprietary H5S.TW alloy provides excellent fatigue resistance and maintains consistent spring rates, while precision-ground flat ends ensure proper seating.\n\nThese springs are sold individually and are available in various spring rates to suit applications from street performance to professional motorsport. It is important to note that unless explicitly stated otherwise, all suspension products are designed for 2WD vehicles only and aftermarket coilovers are not compatible with OEM electronic damping control systems.","brand":"Swift Springs","offers":[{"title":"Default Title","offer_id":52663930749240,"sku":"Z70-152-180","price":101.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687721098.jpg?v=1784330966","url":"https:\/\/store.motormia.co\/products\/70mm-id-x-6-inch-h5s-tw-coil-spring","provider":"MOTORMIA","version":"1.0","type":"link"}
