{"product_id":"metric-coilover-spring-60mm-id-x-4in","title":"Metric Coilover Spring 60mm ID x 4in","description":"The K-Tuned Metric Coilover Spring offers a direct replacement or upgrade option for coilovers requiring a 60mm inner diameter spring. Measuring 4 inches in length, this spring provides a spring rate of 32.0 kgf\/mm (approximately 1,792 lbs\/inch), designed to enhance your suspension's performance. It is crafted from K-Tuned's proprietary HS5.TW material, known for its durability and performance characteristics.\n\nThese springs are sold in pairs, allowing for a complete replacement of your existing coilover springs. While Swift springs are a great way to improve ride quality and customize your coilover's spring rates, it's generally recommended not to deviate more than 2-4K from the original spring rates to ensure optimal damper performance. Some brands, like Silver's kits, can typically accommodate a 4K difference without issue. If you are unsure which springs are compatible with your specific coilover kit, K-Tuned recommends reaching out for assistance.\n\nThe specifications for this particular spring include a 4-inch length, a 60mm inner diameter, and a usable stroke of 42mm with a maximum stroke of 50mm. It's important to note that the color coordination of the spring in images may not reflect the actual length and rate, as it's based on the inner diameter.","brand":"K-Tuned","offers":[{"title":"Default Title","offer_id":52869718147384,"sku":"Z60-102-320","price":202.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/688007427.webp?v=1787917910","url":"https:\/\/store.motormia.co\/products\/metric-coilover-spring-60mm-id-x-4in","provider":"MOTORMIA","version":"1.0","type":"link"}
