Coilover Spring 8in x 2.5in x 125lb Barrel

The SWIFT SPRINGS Coilover Spring 8in x 2.5in x 125lb Barrel is a precision-engineered suspension component designed for automotive enthusiasts and professional builders pursuing advanced chassis tuning. This coilover spring delivers the linear spring rate and consistency required for independent front or rear suspension systems, particularly in street and track-focused vehicle modifications where ride height, damping response, and handling balance demand critical component selection.

Built with SWIFT SPRINGS' reputation for manufacturing reliability, this 125-pound spring rate provides moderate resistance ideal for vehicles running coilover shock absorbers in mid-range suspension geometry setups. The 8-inch free length and 2.5-inch outside diameter barrel design ensure proper packaging in confined engine bays and suspension towers common to performance vehicle platforms. The 125lb rate balances comfort on street driving with sufficient stiffness to control body roll during cornering and maintain predictable load transfer during braking and acceleration events. Spring rate consistency across compression cycles ensures repeatable handling characteristics essential for suspension tuning and track diagnostics.

This coilover spring benefits mechanics, suspension shops, and DIY builders upgrading factory suspension systems on Japanese sport sedans, European platforms, and domestic performance vehicles. Before installation, verify spring length, diameter, and rate compatibility with your specific shock absorber and suspension mounting configuration—mismatched spring rates create handling instability and premature wear on damper internals. Pair this spring with quality adjustable dampers and proper suspension geometry alignment for optimal results.
