This steel spring features a 2.56-inch inner diameter, a 4-inch free length, and a 1,681 lb\/in spring rate converted from the specified 30 kgf\/mm rating. It is supplied individually for use in compatible coil-over applications.\u003cbr\u003eThe coil-over design supports controlled suspension tuning by providing a predictable spring rate and reliable load response. Its compact metric-format configuration is suited to systems that use a 65 mm spring platform, while the high spring rate is appropriate for applications requiring substantial resistance to compression. Verify coil-over hardware, installed height, and vehicle-specific requirements before installation to ensure proper fit and operating clearance.\u003cbr\u003eA durable steel construction provides dependable service in demanding suspension environments. The copper powder-coated finish helps protect the spring surface while providing a clean, professional appearance. The Swift Springs Z65-102-300 is a practical replacement or tuning component for compatible performance suspension assemblies, helping maintain consistent ride-height and handling characteristics when correctly matched to the vehicle and setup.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBrand: Swift Springs\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePart Number: Z65-102-300\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApplication: Coil-over suspension spring\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInner Diameter: 2.56 inches\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFree Length: 4 inches\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSpring Rate: 1,681 lb\/in\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMaterial: Steel\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFinish: Copper powder coat\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eQuantity: Sold individually\u003c\/li\u003e\u003c\/ul\u003e","brand":"SWIFT SPRINGS","offers":[{"title":"Default Title","offer_id":48970759864542,"sku":"SWIZ65-102-300","price":146.74,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/7690\/8766\/files\/SWIZ65-102-300.jpg?v=1788292523","url":"https:\/\/www.racingsupply.ca\/products\/swift-springs-z65-102-300-swift-springs-z65-102-300-coil-over-spring-2-56-inch-id-4-inch-length-1-681-lb-in","provider":"Racing Supply Co.","version":"1.0","type":"link"}
