{"product_id":"4-inch-length-coilover-spring-65mm-id","title":"4-Inch Length Coilover Spring, 65mm ID","description":"It features a 4-inch length, a 65mm inner diameter, and is constructed from K-Tuned's proprietary HS5.TW material for durability and performance. This spring offers a spring rate of 46.0 kgf\/mm (2,576 lbs\/inch), with a usable stroke of 38mm (1.5 inches) and a maximum stroke of 44mm (1.7 inches).\n\nThese springs are sold in pairs and are intended for use with coilovers that utilize a 65mm inner diameter. They can serve as a direct replacement for worn-out springs or as an upgrade to alter existing spring rates. When considering spring rate changes, it's generally recommended by most coilover brands not to deviate more than 2-4K from the original rates to ensure optimal damper performance. However, Silver's kits can typically accommodate a 4k rate difference without issue.\n\nIf you are uncertain about the correct spring specification for your Silver's kit or other coilover systems, it is advisable to consult with the manufacturer for guidance.","brand":"K-Tuned","offers":[{"title":"Default Title","offer_id":52869724438840,"sku":"Z65-102-460","price":119.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/688007469.webp?v=1787917939","url":"https:\/\/store.motormia.co\/products\/4-inch-length-coilover-spring-65mm-id","provider":"MOTORMIA","version":"1.0","type":"link"}
