SWIFT SPRINGS Z60-178-140 Swift Springs Z60-178-140 Coil-Over Spring, 785 lb/in Rate, Blue Steel

The Swift Springs Z60-178-140 coil-over spring is engineered for performance suspension applications that require consistent spring behavior and dependable support. Built from high-quality spring steel, this coil spring delivers a firm 785 lb/in spring rate, equivalent to approximately 14 kgf/mm, for applications requiring precise control over suspension movement. Its coil-over configuration makes it suitable for compatible racing, track, and high-performance suspension systems.
The spring features a 2.36-inch inside diameter and a 7-inch free length for use with matching coil-over components. Its carefully formed coils are designed to provide predictable compression characteristics and repeatable performance under demanding driving conditions. Whether used during a new suspension build or as a replacement spring, the Z60-178-140 helps support accurate suspension tuning and consistent vehicle response.
A blue powder-coated finish provides a durable protective surface while giving the spring a clean, recognizable appearance. The finish helps resist typical handling wear and supports long-term service in properly maintained suspension systems. This Swift Springs component is sold individually, making it a practical choice for replacing a worn spring or configuring a vehicle with a specific spring-rate combination. Verify coil-over compatibility, spring seat requirements, and suspension setup before installation to ensure proper fitment and performance.
