The Swift Springs Z65-203-180 coil-over spring is engineered for suspension applications that require consistent spring performance, dependable construction, and precise response. Manufactured from high-quality steel, this spring is designed to work with compatible coil-over suspension systems and provide controlled support during acceleration, braking, cornering, and changing road conditions. Its calibrated spring rate helps suspension builders achieve predictable handling characteristics while maintaining reliable performance throughout repeated use.
The spring features an 18 kgf/mm rate, equivalent to approximately 1,008 lb/in, making it suitable for performance-oriented suspension setups that require substantial support. The coil-over configuration allows it to integrate with compatible adjustable suspension assemblies, giving installers and tuners greater flexibility when optimizing vehicle ride height, handling balance, and suspension response. As with all suspension components, compatibility should be confirmed with the coil-over body, spring perch, and the intended vehicle application before installation.
A durable copper powder-coated finish helps protect the steel surface from everyday exposure while providing a clean, professional appearance. This Swift Springs component is supplied individually and is well suited for motorsport, track, performance street, and custom suspension projects where repeatable spring characteristics are important. The Z65-203-180 part number provides a reliable reference when matching the spring to a specific Swift Springs application or replacing an existing component. Professional installation is recommended, and the spring should be used only within the operating requirements of the compatible suspension system.
