SWIFT SPRINGS Z60-152-040 Swift Springs Z60-152-040 Coil-Over Spring, 224 lb/in Rate, Blue Steel

The Swift Springs Z60-152-040 is a precision coil-over spring designed for suspension systems that require consistent support, predictable handling, and dependable performance. Built from high-quality spring steel, this coil spring delivers a 224 lb/in spring rate, equivalent to the specified metric rate, for controlled suspension response in demanding street, track, and performance applications. Its coil-over configuration makes it suitable for compatible adjustable suspension assemblies and replacement setups.
The spring features a durable blue powder-coated finish that helps protect the steel surface from everyday handling, installation wear, and environmental exposure. The coating also provides quick visual identification within a suspension setup while maintaining the professional appearance expected from Swift Springs components. Each spring is produced for reliable load management and repeatable behavior, helping suspension systems maintain balanced operation through cornering, braking, acceleration, and changing road conditions.
Designed as an individual replacement or tuning component, the Swift Springs Z60-152-040 allows suspension builders and enthusiasts to fine-tune vehicle response without replacing an entire coil-over assembly. Verify spring compatibility with the vehicle, damper, tender spring, perch, and intended suspension travel before installation. Proper setup should account for vehicle weight, corner weights, motion ratios, preload requirements, and the manufacturer’s recommended operating range. This spring is supplied individually and is an effective choice for performance suspension maintenance, replacement, or rate adjustment where its specifications match the application.
