Installers and suspension technicians favor SWIFT SPRINGS coil-over springs for their reliability in aftermarket coil-over kits and custom suspension builds. The 3-inch ID design pairs seamlessly with standard 2.5-inch shock bodies commonly found in performance coil-over assemblies, ensuring proper seating and load transfer. Weighing 3.48 lbs per spring, this component is ideal for single-spring replacement or full suspension overhauls. Professional installation is recommended to ensure correct preload, ride height geometry, and spring centering for optimal performance and longevity.
