Coilover Spring 8in x 2.5in x 425lb

The SWIFT SPRINGS Coilover Spring 8in x 2.5in x 425lb is a precision-engineered suspension component designed for automotive enthusiasts and professional mechanics building high-performance coilover systems. This linear-rate spring serves as the backbone of modern adjustable suspension setups, allowing drivers to fine-tune ride height, stiffness, and damping characteristics independently.

Specified at 425 pounds per inch, this linear spring rate represents a mid-range stiffness suitable for road course driving and street applications without excessive harshness. The 8-inch free length and 2.5-inch outer diameter dimensions indicate a compact profile optimized for modern MacPherson strut and double-wishbone configurations where packaging space is critical. Swift Springs' manufacturing precision ensures consistent spring rates across production runs, which is essential for maintaining balanced suspension geometry when paired with matching springs on opposite corners.

This coilover spring is ideal for builders and mechanics constructing custom suspension systems for Japanese, European, and American platform applications. Its lightweight design minimizes unsprung mass, improving tire contact patch consistency and reducing suspension travel time during load transitions. With its versatile application, this spring is perfect for upgrading street cars, track-focused platforms, or daily drivers needing responsive handling.
