Coil-Over Spring 20in x 5in x 80lb 2.5in ID

The Coil-Over Spring 20in x 5in x 80lb 2.5in ID from SWIFT SPRINGS is designed for serious suspension builders and performance enthusiasts engaged in custom lowering, coil-over conversion, or competitive motorsport builds. This precision-wound compression spring is engineered to provide the progressive rate and consistency necessary for optimizing ride height, load capacity, and handling geometry across various vehicle types.

Constructed with SWIFT SPRINGS' high-quality spring steel and advanced heat-treat processes, this spring features an 80-pound rate that offers medium stiffness, making it suitable for both daily-driven and track-focused applications without excessive harshness. The 20-inch free length and 2.5-inch inner diameter are compatible with most modern double-adjustable shock bodies and universal coil-over sleeves, while the 5-inch outer diameter ensures reliable coil bind clearance.

This coil-over spring is ideal for adjustable dampers and custom suspension geometries on import sport compacts, drift platforms, autocross machines, and road racing builds where precise spring rate matching is essential. Whether you're fabricating a complete coil-over kit or replacing worn OEM springs, this component provides the foundation for achieving repeatable, tuned suspension performance.
