Coilover Spring 8in x 2.5in x 375lb

The SWIFT SPRINGS Coilover Spring 8in x 2.5in x 375lb (model 080-250-375) is a precision-engineered suspension component designed for performance vehicle builds, lowering kits, and custom coilover assemblies. Built for enthusiasts and professionals who demand precise spring rates and consistent ride control, this coil-over spring integrates seamlessly into custom suspension systems where predictable load handling and adjustable ride height are critical. Whether you're building a street-performance setup, competition suspension, or upgrading factory coilovers, this 375 lb/in spring rate delivers the responsive handling characteristics serious builders require.

This coilover spring features an 8-inch free length and 2.5-inch inner diameter, manufactured from high-tensile steel and finished with a black powder coat for corrosion resistance and durability under demanding conditions. The 375 lb/in spring rate—measured in pounds per inch of compression—provides moderate stiffness suitable for both street and light track use, balancing comfort with body control without bottoming out under normal driving loads. The compact 4.5 x 4.5 x 11.5-inch package design fits standard coilover kits and allows proper clearance within suspension towers, while the 2.91 lb weight keeps unsprung mass minimal for improved responsiveness.

This spring is ideal for builders creating custom coilover assemblies on sport compacts, trucks, and performance cars where factory suspensions limit adjustability. When paired with quality dampers and proper alignment, the 375 lb/in rate maintains consistent spring preload across a range of vehicle weights and modifications. Installation typically requires removal of the factory coilover or strut assembly; consult your vehicle's suspension geometry and intended use case to confirm compatibility with shock absorber length and mounting diameter.
