UMI 1978 - 1988 GM G-Body Lowering Spring, Front, 1” Lowering

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 springs are wound from 5160 CrSi premium wire and feature a linear 600 lb/in rate. UMI’s front springs are stiffer than stock to provide increased performance with decreased body roll and a lower center of gravity. 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 as well as LS power (lightened cars may require spring trimming). The front springs are also suitable for full weight Big Block applications when ¼” nose down rake is desired. They have a tough black powder coat finish and UMI proudly manufactures these premium quality springs in the USA.

• Consistent rates and only the best materials (premium Chrome Silicon wire) ensure your cars sits properly for years to come.
• Linear spring rates (600 lb/in front, 130 lb/in rear) provides a firm yet comfortable ride and incredible handling.
