UMI Performance 67-72 GM A-Body 1in Lowering Spring Set

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 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. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving/cruising. The ride height is engineered for a 1” lowering with standard SBC, Pontiac 400 and aluminum head/intake Big Block Chevy 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 springs in the USA.
