SWIFT SPRINGS Z65-178-180 Swift Springs Z65-178-180 Coil-Over Spring, 2.56 in ID, 7 in Length, 1,008 lb/in Rate

The Swift Springs Z65-178-180 coil-over spring is engineered for performance suspension applications that require consistent spring behavior, precise fitment, and dependable control. Designed with a 2.56-inch inside diameter and a 7-inch free length, this spring is suited for compatible coil-over systems using a 1,008 lb/in spring rate. Its carefully manufactured steel construction provides the strength needed for demanding street, track, and competition environments.
The linear spring design delivers predictable resistance throughout suspension travel, helping support controlled chassis movement and repeatable handling characteristics. The 1,008 lb/in rate is intended for applications that require substantial support and reduced suspension compression under load. Proper spring selection should always be based on the vehicle, damper configuration, corner weights, suspension geometry, and intended use to ensure the best balance of ride control and performance.
A durable copper powder-coat finish helps protect the steel spring from everyday exposure while providing a clean, professional appearance. This Swift Springs coil-over spring is supplied individually and is identified by part number Z65-178-180 for straightforward product selection and replacement. Before installation, verify compatibility with the spring perch, damper body, retaining hardware, and the rest of the suspension system. Professional installation and appropriate suspension setup are recommended to help maintain safe, reliable operation.
