SWIFT SPRINGS Z65-127-080 SWIFT SPRINGS Z65-127-080 Coil-Over Racing Spring, 448 lb/in, Copper Powder Coat

The SWIFT SPRINGS Z65-127-080 coil-over spring is engineered for performance suspension systems that demand consistent response, dependable support, and precise tuning. Built for metric coil-over applications, this spring delivers an 8 kgf/mm rate, equivalent to approximately 448 lb/in, helping suspension builders achieve predictable handling characteristics across demanding driving conditions. It is supplied individually for custom suspension setups, replacement needs, and carefully matched spring combinations.
The spring is manufactured from high-quality steel selected for strength, durability, and resistance to fatigue under repeated compression cycles. Its coil-over design supports use in racing, track, autocross, performance street, and other motorsport applications where spring behavior and repeatability are essential. The accurately formed coils help maintain consistent operation while the controlled spring rate supports suspension tuning based on vehicle weight, chassis balance, tire performance, and driver preference.
A copper powder coat provides a durable protective finish while giving the spring a clean, distinctive appearance. This coating helps shield the steel surface from common environmental exposure encountered during installation and use, while maintaining the professional finish expected from SWIFT SPRINGS components. The Z65-127-080 is intended for properly matched coil-over hardware and should be selected according to the vehicle, damper, suspension geometry, and manufacturer recommendations. Confirm compatibility with the complete suspension system before installation.
