Official Release:

UMI Performance, Inc. is pleased to announce the availability of our new factory height spring kit for 1964-1972 GM A-Body applications. These springs are designed to add modern handling and a crisp ride while maintaining the factory musclecar appearance. Our front springs are wound from 5160 CrSi premium wire and feature a linear 530 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 A-body. The ride height is engineered to be level with standard SBC, Pontiac 400 and aluminum head/intake Big Block Chevy as well as LS power (lightened cars may require spring trimming). They have a tough, black powder coat finish and UMI proudly manufactures these premium quality springs in the USA.
