Consistent rates and only the best materials (premium Chrome Silicon wire) ensure your cars sits properly for years to come.
Linear spring rates (600 lb/in front, 130 lb/in rear) provides a firm yet comfortable ride and incredible handling.
A spring is a spring right? Wrong! When UMI chose to manufacture our own line of springs we went all out. Designed in conjunction with a leading Sprint Cup chassis engineer, these springs are the best in the business. Our front springs are wound from 5160 CrSi premium wire and feature a linear 600 lb/in rate. The rear springs are wound from 9254 CrSi premium wire and feature a linear 130 lb/in rate. The linear rate provides consistent handling characteristics which are important for Auto-x and Pro-Tour applications while the increase in stiffness reduces body roll and prevents the floating feeling so common with the G-Body. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving/cruising. The ride height is engineered for a 2 Lowering with standard SBC as well as LS power (lightened cars may require spring trimming). The front springs are also suitable for full weight Big Block applications when nose down rake is desired. They have a tough, black powder coat finish and UMI proudly manufactures these premium quality springUSA.
