The Swift Springs Z65-127-120 is a metric coil-over spring engineered for performance suspension applications that demand consistent response, dependable support, and precise spring behavior. Designed with a metric coil-over configuration, this spring is well suited for racing, track-day, autocross, and other applications where suspension tuning and repeatable handling are essential. Its 12 kgf/mm spring rate is approximately 672 lb/in, providing a firm, controlled suspension response for demanding driving conditions.
Constructed from durable spring steel, the Z65-127-120 is designed to maintain its performance characteristics through repeated compression cycles and intensive use. The copper powder-coat finish provides a distinctive appearance while helping protect the spring surface from routine environmental exposure, handling, and installation-related wear. This finish also supports a clean, professional presentation when the spring is installed in an exposed or competition-oriented suspension system.
Swift Springs is recognized for producing high-performance suspension components with a focus on precision, consistency, and tuning flexibility. The Z65-127-120 coil-over spring is supplied individually and is intended for use with compatible coil-over hardware and suspension assemblies. Confirm spring compatibility, installed height, travel requirements, and rate selection with the vehicle or damper manufacturer before installation. For suspension setups requiring a firm metric spring with a clearly defined performance rate, this Swift Springs component offers a reliable option for building a responsive and carefully balanced system.
