UMI Performance 3050F 78-88 GM G-Body Front 1in 70-81 F-Body 2-1/2in Lowering Spring

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.
V6 Turbo Grand National may require spring trimming due to lower engine weight.
