If it’s time to lower your 64-66 GM A-Body, it should be done with the right tools for the job. Drop yours a full two inches with UMI Performance springs. Improve your handling and steering response. Details below.

Official Release:

UMI Performance, Inc. is pleased to announce the availability of our new 2” lowering spring kit for 1964-1966 GM A-Body applications. 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 2” 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 slight nose down rake is desired. UMI’s springs are supplied with a tough black powder coat finish. UMI proudly manufactures these premium quality springs in the USA.
