SWIFT SPRINGS Z65-203-070 SWIFT SPRINGS Z65-203-070 Coil-Over Spring, 7 kgf/mm Rate, Steel, Copper Powder Coat

The SWIFT SPRINGS Z65-203-070 is a metric coil-over suspension spring engineered for applications that require consistent spring performance, reliable fitment, and durable construction. With a 7 kgf/mm spring rate, equivalent to approximately 392 lb/in, this spring delivers firm, predictable support for performance-oriented suspension systems and coil-over assemblies. Its design is intended for use with compatible metric coil-over hardware and spring seats.
The spring is manufactured from steel to provide the strength and resilience needed for repeated compression cycles and demanding suspension operation. A copper powder-coated finish helps protect the surface from general environmental exposure while providing a distinctive appearance that complements custom and performance suspension builds. The finish also supports easier identification during installation and maintenance without changing the spring’s intended function.
As an individual replacement or installation component, the SWIFT SPRINGS Z65-203-070 is suitable for builders, tuners, and suspension professionals seeking a dependable spring with a defined rate. Verify coil-over compatibility, spring seat requirements, and available travel before installation. Proper setup should account for vehicle weight, corner loading, damper adjustment, ride-height goals, and the manufacturer’s recommended operating range. Supplied as one steel coil-over spring, this SWIFT SPRINGS component offers a practical solution for suspension upgrades, replacement needs, and carefully matched spring-rate configurations.
