# UMI Performance 67-72 GM A-Body Factory Height Springs Rear 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 designed to add modern handling and a crisp ride while maintaining the factory muscle car appearance. 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 A-body. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving and general cruising. They have a tough, black powder coat finish and UMI proudly manufactures these premium quality springs in the USA.
