UMI Launches 1" and 2" Lowering Spring Kits For G-Bodies

UMI adds to its line of G-body support with new 1″ and 2″ lowering springs for the 1978-88 G-body platform. Get your coupe riding low and agile with these black powder coated springs, and get used to feeling better handling around autocross courses or twisty mountain roads. See more details below.

Official Release:

UMI Performance, Inc. is pleased to announce the availability of our new 1” and 2” lowering spring kit for 1978-1988 GM G-Body applications. Our front springs are wound from 5160 CrSi premium wire and feature a linear 600 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 G-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” or 2” lowering with standard SBC and aluminum head/intake BBC as well as LS power (lightened cars may require spring trimming). Lowering springs have a tough, black powder coat finish and UMI proudly manufactures these premium quality springs in the USA.
