UMI Performance 64-66 GM a-Body Lowering Spring Set Rear

No more floating feeling. Suitable for Pro-Tour, Auto-x and general cruising. As an industry leader in the muscle car suspension industry, UMI is proud to bring you the best spring in the business. Linear spring rates (530 lb/in front, 130 lb/in rear) provides a firm yet comfortable ride and incredible handling. Consistent rates and only the best materials (premium Chrome Silicon wire) ensure your cars sits properly for years to come. 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. These 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 A-body. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving/cruising. They have a tough black powder coat finish and UMI proudly manufactures these premium quality springs in the USA. 4053R - 1964-1966 GM A-Body 2" Lowering Spring Set, Rear.
