UMI Performance 64-72 GM a-Body 78-88 G-Body Lowering Spring Rear

No more floating feeling. Suitable for Pro-Tour, Auto-x and general cruising. Linear spring rates (530 lb/in front, 130 lb/in rear) provides a firm yet comfortable ride and incredible handling. As an industry leader in the muscle car suspension industry, UMI is proud to bring you the best spring in the business. 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. 4051R - 1964-1972 GM A-Body 1978-1988 G-Body 2" Lowering Spring, Rear.
